User Exits for Substitution

[mateusz_wrobel]

Hi,

I am new in ABAP. Can someone advice how to write/improve exits ? Unfortunately below do not work in FB50/FB01:

if bseg-mwskz is initial.
move 'z5' to bseg-mwskz.
endif.

if bkpf-bldat is initial.
move bkpf-budat to bkpf-bldat.
endif.

Did you read the documentation available in SPRO transaction and in online documentation?

1. In your example you actually don't need user exits
2. 'z5' cannot be a correct value. (check domain for lowercase allowed)
