Hi ,

In PBO event check lgpla as initial.

e.g. if lgpla is initial.

endif.

Hi Vijay,

In the screen painter I can see the name of the field as LUQA-LGPLA as I have taken it from the dictionary of that table.In the flow logic of that screen in the PAI i have given in the following way.

DATA: V_LGPLA TYPE LQUA-LGPLA.

IF LQUA-LGPLA IS NOT INITIAL.

V_LGPLA = LQUA-LGPLA.

But it is giving error as field LQUA-LGPLA is unknown.

deaclare

Tables: LQUA. in TOP Include.

It won't give that error.

Hi,

Give this in your TOP include file.

TABLES: LQUA.

This is the reason for the error. This statement is required so that data can be transferred between the screen fields and ABAP dictionary and the program.

Hi, You can do like this,

IF lqua-lgpla IS IS INITIAL
 MESSAGE 'the field is initial' TYPE 'I'.
ENDIF.

If you want to check it after a button click then place it in PAI. Thanks, Sri.

Hi Abaper12345,

Declare table lqua as tables in top include.

tables : lqua -- in TOP include.

Then if you want to put any validation on this field, you can write your validation in PAI event.

FIELD lqua-lgpla MODULE check_1 ON REQUEST.

In module, check_1, check whether lqua-lgpla is initial and give your processing logic as per requirement.

IF lqua-lgpla is initial.

• Processing logic

endif.
