How to control custom fields

[former_member295881]

Hello Experts,

I've added 3 custom fields in Sales Order transaction. For TCODE VA01 and VA02 my fields are enable (which is required) but in case of VA03 fields are also editable. Please advice what I should change to disable my custom fields like other fields if TCODE is VA03.

Many thanks in advance.

in MV45AFZZ, you can try below code.

FORM USEREXIT_FIELD_MODIFICATION.

if sy-tcode = 'VA03'.

if SCREEN-NAME = 'VBAK-ZZFIELD1'.

     SCREEN-ACTIVE = 0.

      Modify screen.

endif.

endif.

ENDFORM.
