Today we will see how easy it is to set up the Layout for the ALV which was created using the reference of the CL_SALV_TABLE calss. Previous discussions in this series were:
Normal 2D Display
Add default PF Status
Add custom PF Status
All these discussions can be found under Tutorials > SALV Table display
Layouts provides greate flexibility to users for saving their own layouts which contains settings like - sum, subtotal, filter, sort etc. This provides a great degree of advantages to the ALV reports. We can add much more in this if we can provide the option from which user can select the Layout and generate his/her report.
We will request our ALV instance for the instance of the CL_SALV_LAYOUT. This class contains all the necessary methods which can be helpful for the Layout settings.
Here is the code snippet to which provides the ADD-ON code to our Base program. The base program can be found in the SALV Model 1: Normal ALV Table Display.
UML diagram for the test program will be like:

* In this section we will define the private methods which can

PRIVATE SECTION.
METHODS:

co_alv TYPE REF TO cl_salv_table.

* In this area we will call the methods which will set the
* different properties to the ALV
*
* Setting up the PF-Status
CALL METHOD set_pf_status
CHANGING
co_alv = o_alv.

* Setting up the Layout
CALL METHOD set_layout
