When we download the data from the SAP using FMs like GUI_DOWNLOAD or WA_DOWNLOAD (absolute); or the method of class CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD and open that file in the Microsoft Excel, we loose some important information like leading zero, long numbers will come as exponents. Most of the times we don't want this because we will use this File as input of some program or we will use it for future analsys.

When we use the .xls extension to save the file and open it directly in the Excel, the file will look like this:


We will see how to stop Excel removing our precise information which we have downloaded from SAP. We need to follow this Steps:
1. We will save our file with .txt extension instead of the .xls extension.

2. Start Excel. Start > Run > Enter Excel.

3. Open the downloaded file by Selecting it from the Open File dialog box.

4. Once we open the file, excel will bring "Text to column" wizard.

5. Select the "Delimilated" option in the first screen. Move to the 3rd Step of the wizard by pressing the Next button two times.


6. In the 3rd step, select all the columns. To select all the columns do like: Click on first column, Hold the shift key, scroll to last column, click on last column. This way all the columns gets selected. The colums which got selected will have black background. Now, select the Option "Text" in the format.


7. Finish the Wizard.

Our file after opening in Excel will look like this:



This is the code snippet I have used to generate the test file.

Knowledge Management or Enterprise Knowledge Management provides central and role-based access to the information in your company and creates a connection between structured business data and unstructured documents.

Enterprise Knowledge Management contains the tools to integrate different data sources and to create, administer, and distribute information. It allows consolidation and integration of intranet platforms and makes available integrated search technology that takes into account all data stores in your company.

In Knowledge management there is some thing called Knowledge warehousing...

Under which you have

a) Document management service &

b) Content Mnagement service

Its part of Netweaver 2004s release..

The technological components required or which are integral part of KM are:-

i. Application Server Java (AS-Java)

ii. Application Server ABAP (AS ABAP) – only required for the Documentation, Manuals, and Training Material Management

iii. Enterprise Portal (EP)

iv. Stand-alone engines:

v. Search and Classification (TREX) and of course BIContenet also.

The intended purpose of Knowledge Management:

- Receipt of relevant, role-based, and personalized information

- Automatic notification about new or changed information

- Quick finding of information using advanced search functions

- Direct options for reacting to information

- Display of information from different data sources on a common user interface

- Simplified exchange of information between users

- Clear structuring due to automatic classification

- Means of storing and efficiently using unstructured information

- Integration of your existing information landscape

- Or a complete switch to the KM capabilities of SAP NetWeaver

- Implementation of a consistent Content Management system

- Administration of business applications and Content Management in a single platform

- Use of integrated search technology for company-wide stores

What are the scope of work when SAP is implement?

You should have a Project manager from your company, who will work or should work closely with the implementing Company Project Manager.

The Implementing company will supply the Technical/Functional Consultants. Your company should provide so-called "Super Users / Key Users. These are persons within the company who know the business and its processes inside out.

The Key Users will work closely with the Technical Consultants in designing the companies Business Process to fit with SAP.

The Technical consultants should pass on their knowledge to the Key Users. The Key User will train the End Users, so they must be also trained in SAP Business Process, this is either done by the Implementing company or your company can
send them to SAP training.

The driving person here is your Company Project Manager, in any case all company persons involved in the Implementation project should be on the project 100 percent.

You should setup five phases :
1. Preparation
2. Blueprinting,
3. Realization
4. Preparation Go Live
5. Go Live/Support

From the Project Management side, there are many thing that must be set up prior to Blueprinting, such as Project Charter, Project Plan, Risk Management Plan, Change Management plan etc.

As far as a SOW, this is part of your Charter and there are many Templates of such documents, you need more than just the template, you must know how to analysis your overall environment (Company goals, landscape, Business objectives etc)
in coming up with the Scope. More than one person is involved in the SOW defination.

BASIS is like an Operating System for R/3.

We can say that BASIS is a middleware between ABAP/4 (Advanced Business Application Programming) and the computer Operating system.

R/2 system was mainframe based. SAP ported it to client/server environment. To do this SAP created BASIS. Creating BASIS enabled ABAP/4 code to run on other platforms as well.

ABAP/4 programs cannot run directly on an Operating system (like Windows). It requires set of programs (collectively known as BASIS) to load and intreprete its input and output.

Without BASIS programs ABAP/4 programs cannot run.

You can relate BASIS to ABAP/4 programs, like Windows is to Windows programs.

To install BASIS, the installer runs the program "r3inst" at the command prompt level of O/s. Like most installs, this also creates a directory structure and copies set of executables into it (like for e.g. when we install the Windows operating system in our computer, it creates a directory structure like program files, windows etc..and copies set of executables into it). These executables taken together form BASIS.

Thus, ABAP/4 programs run within the protective BASIS environment. They are not executables that run on an Operating system. Instead BASIS reads ABAP/4 code and intrepretes it into Operating system instructions. ABAP/4 programs do not access O/S functions directly. Instead they use the BASIS function to perform the file input/output operation and display data in windows.

1. How the tickets in production support are resolved?
2. Give some examples with solutions?

What are the types of ticket and its importance?

This depends on the SLA. It can be like:

1. Critical.
2. Urgent.
3. High.
4. Medium
5. Low.

The response times and resolution times again are defined in the SLA based on the clients requirement and the charges.

This is probably from the viewpoint of Criticality of the problem faced by the client as defined by SAP.

1) First Level Ticketing:

Not severe problem. Routine errors. Mostly handled by Service desk arrangement of the company (if have one).

Eg: a) Say Credit limit block in working on certain documents?
b) Pricing Condition Record not found even though conditions are maintained?
c) Unable to print a delivery document or Packing list?

PS: In the 4th phase of ASAP Implementation Methodology( i.e Final Preparations for GO-LIVE) SAP has clearly specified that a Service desk needs to be arranged for any sort of Implementation for better handling of Production errors.

Service desk lies with in the client.

2) Second Level Ticketing:

Some sort of serious problems. Those Could not be solved by Service Desk. Should be referred to the Service Company (or may be company as prescribed in SLA).

Eg: a) Credit Exposure (especially open values) doesn't update perfectly to KNKK Table.
b) Inter company Billing is taking a wrong value of the Bill.
c) Need a new order type to handle reservation process
d) New product has been added to our selling range. Need to include this into SAP. (Material Masters, Division attachements, Stock Handling etc.)

3) Third Level Ticketing:

Problems could not be solved by both of the above, are referred to Online Service Support (OSS) of SAP Itself. SAP tries to solve the Problem, sometimes by providing the perfect OSS Notes, fits to the error and rarely SAP logs into our Servers (via remote log-on)for post mortem the problem. (The Medical check-up client, connections, Login id and Passwords stuff are to be provided to SAP whenever they need or at the time of opening OSS Message.)

There are lots of OSS Notes on each issue, SAP Top Notes and Notes explaining about the process of raising a OSS Message.

Sometimes SAP Charges to the client / Service company depending on the Agreement made at the time of buying License from SAP.

Eg: 1) Business Transation for the Currency 'EUR' is not possible. Check OSS Note - This comes at the time of making Billing.
2) Transaction MMPI- Periods cannot be opened – See OSS Note.

There are many other examples on the issue.

4) Fourth Level Ticketing:

Where rarely, problems reach this level.

Those problem needs may be re-engineering of the business process due to change in the Business strategy. Upgradation to new Version. More or less this leads to extinction of the SAP Implementation.

SAP have disabled the session takeover once you upgrade to 4.6x.

Definitively SAP have blocked the functionality from the kernel.

The original program RSM04000 still exists but it doesn't work anymore.

Alternatively, you can used software like Microsoft NetMeetings.

However, in some of the SAP Version 4.x, you can still echo the user session.

This is how it goes :-

How to Create the Echoed Session :-

a) Make sure the User you want to Echo to is logged onto the same system you are logged onto.
b) Rel prior to 4.6B, Execute the SM04 transaction from your logon.
Rel 4.6B and later, Execute program RSM04000 from your logon.
c) Single Mouse-click to the command input area and key in 'slon' (without the quotes).
d) Single Mouse-click to the Userid you want to 'Echo-on' to.
e) Hit enter.
f) You will now be echoing your screens to the other User.
Note: You have not taken over their original session, you have created a new session for the echo.

How to Terminate the Echoed Session :-

a) Return to your SM04 screen display.
Single Mouse-click to the command input area and key in 'slof' (without the quotes).
b) Single Mouse-click to the Userid you want to 'Echo-off'.
c) Hit enter.

Note: This will remove your Echoed session screen from the Users screen, but leave the User logged on with their original session.

To download any software from SAP Market place, first of all, you will need to be an existing SAP customer. If you are one of those that are authorized to access the SAP site, you'll be assigned an OSS ID which allowed you to report problems, search for SAP notes as well as request SAP related software on behalf of your company.

Sometimes, it is necessary to send emails with the Formatting when we are sending the email using SAPConnect.

Formatting is necessary to display proper information. For example, Information is formatted repesentation of the Data. If no formatting, no information. Same way, if we send the unformatted contents, than it will make wrong impression.

In ABAP also, using the SAPConnect function modules we can send the highly formatted contents in the Message body. For this purpose, we need to use HTML. HTML will represent our data in the formatted way on receipient side.

While filling up the Body of the message (CONTENTS_TXT), we fill it up with the HTML code. After filling up the content, we need to tell the system that we are sending the HTML data instead of the pure text. Generally, we specify the DOC_TYPE in PACKING_LIST as the TEXT. But for this purpose, we will pass HTML since our data is in HTML. Than we will pass all the information to the Function Module SO_NEW_DOCUMENT_ATT_SEND_API1.

Describes a way to create a dynamic internal table from coding. This is also can be used when RTTS is not supported or class CL_ALV_TABLE_CREATE is not available.

Previously, we have seen:

Dynamic Internal Table Creation using RTTS

Dynamic Internal Table with Deep structure using RTTS

Dynamic Internal Table creation using class CL_ALV_TABLE_CREATE

Recently, one of my friends asked me for the solution to create Internal Table. The problem was his system was not able to support the RTTS nor it has the class CL_ALV_TABLE_CREATE. Actually, I had developed this solution in early days when I was working on system 4.6B where I haven't RTTS nor the ALV class.

Here is the solution:

Today we will discuss about the Design Pattern: Model-View-Controller, which is also very famous by its abbriviation MVC. By definition, MVC is to isolate the business logic from the User Interface which gives great degree of flexibility to change business logic independently to the user interface and vice versa.

In MVC, User Interface acts as the View; Business logic acts as the Model and the link which provides the link between the View and Model is known as the Controller. In real time business, MVC is used anywhere, where users have a choice to select his or her view. For example, Windows Media Player, Gmail or Yahoo mail and so on. All these type of applicaiton provides us the option to select the skin as per our choice.

Let's take an example: We have to develop one Sales report for our corporate intranet. This report must have the option to display the sales data in the classical report format; different charts - pie, bar, line or both - report & chart and it must be based on the User's choice. This type of requirements where we can easily separate the Business logic and the views are the best candidates for MVC.

Generally, Model sends the data to controller and controller will pass that data to Views and views will display the data as per their nature. In SAP, our business logic(model) will not send data unless and untill View request for an data becase ABAP is event driven language. Like user has to run some transaction to get the data, means application view has to initiate the process and ask for the data from the Model. In this requesting process, Controller will help the view to be apart from the model.

UML diagram of the typical MVC application would be:


As we can see here, Model will send the data to the Controller and controller will pass that information to the View. Now, its a view's responsibility to create a user specific view - Report, or Chart.


Advantages:
Since both our business logic and view logic are different, we can easily change any of the logic without interepting the other part.

In this post, we will see how we can implement the MVC (Model-View-Controller) design pattern in ABAP using the Objects. If you have not read the previous discussion about MVC: ABAP Objects Design Patterns - Model View Controller (MVC) Part 1, than I strongly recommond to read that before moving forward.

To implement the MVC, we will create two applications - One will generate an output in ALV and other will generate an output Smartforms. We will put our business logic in the MODEL class. We will create one CONTROL class to establish control between Model and Views.

The UML diagram for any of the application would be like:


Our business logic for this example is fairly simple - select the Sales Orders from the VBAK which were created in last ten days. The public method GET_DATA in the class ZCL_MODEL will act as the business logic. Additionally, this class has the public attribute T_VBAK which will be set by the GET_DATA and hold our data from the table.
Model Method Definition

Code Snippet of method GET_DATA

* Parameters * Importing IR_ERDAT TYPE TPMY_R_DATE Ranges for date * METHOD get_data. * * Get data and save into attribute T_VBAK SELECT * FROM vbak INTO TABLE t_vbak WHERE erdat IN ir_erdat. * * ENDMETHOD.

Our controller class ZCL_CONTROL will have a method GET_OBJECT which will give us an object of the model class. We require a public attribute which can refer to the object created in the method GET_OBJECT.
Controller Method definition:


Controller Attributes definition:

Code Snippet for method GET_OBJECT

* Parameters * Importing IF_NAME TYPE CHAR30 Model class name * METHOD get_object . * DATA: lo_object TYPE REF TO object. * * Generic object reference to importing class CREATE OBJECT lo_object TYPE (if_name). IF sy-subrc = 0. * Downcasting to assign generic object to O_MODEL o_model ?= lo_object. ENDIF. * ENDMETHOD.

In the next post we will see, how we will use the controller class in our view and access the business logic encapsulated in Model class.

In this post, we will see how we can implement the Views which will access the Controller and model which is encapsulated in the controller. This post is in continuation of previous post: ABAP Objects Design Patterns - Model View Controller (MVC) Part 2.

For our first Application view will be ALV output. To get the data for the ALV into the application, we will use the reference of the MODEL class created in the Controller. This way our model class is entrily separated by the view.
