Make (LDB)PNP Fields obligatory on selection-screen

[former_member181966]

I am using LDB PNP.. I want to make some fields of PNP as obligatory. How Can I do that?

So far I am doing the following...

<b>Initialization.

PNPABKRS-LOW = '?'.

Append PNPABKRS.

At selection-screen.

if PNPABKRS-LOW is initial.

PNPABKRS-LOW = '?'.

Message e100(z01).

endif.</b>

What you suggest ?

Thanks

You have to do this way,

AT SELECTION-SCREEN OUTPUT.

  LOOP AT SCREEN.
    IF SCREEN-NAME = 'PNPABKRS-LOW '.
      SCREEN-REQUIRED = 1.
      MODIFY SCREEN.
    ENDIF.
ENDLOOP.
