in ALV output on the menu towards the last you will find a button related to ALV CHANGE LAYOUT such that you will display the fields as per your order of sequence

This is user specific

Nothing will happen if you validate the fields in Start of selection

But it is good practice to validate the selection screen fields in the event AT selection screen itself

1) use:

 x_save = 'X'.
  gs_variant-report     = sy-repid.

  CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'
       EXPORTING
            I_STRUCTURE_NAME = c_tabname
            IS_VARIANT       = gs_variant
            IS_layout        = lay
            I_SAVE           = x_save
       TABLES
            T_OUTTAB         = gridtab
       EXCEPTIONS
            OTHERS           = 1.

2) better mak validations on input-fields at event:

at selection-screen...

Hi Ravi,

1. Use LAYOUT button

2. Validation in Start of Selection : If we raise an error message after a validation fails, then user is redirected to selection screen of the program.

Hi Ravi,

Solutions :

1. Using ALV layout.

2. If user enter wrong values at selection screen.

It would not restricted to selection screen. Compiler would go into start of selection and it would not stop processing.

thaty validation are always done at <b>at selection screen event.</b>

Reward pointsif helpful.
