Modification in user Exit PPCO0006 (EXIT_SAPLCOZF_003)

Dear all

I try to fill a fiel in the user exit PPCO0006 (EXIT_SAPLCOZF_003) simply as this:

afpod_imp-ablad = 'XXX'...

but nothing happens.

i see that there is an exporting parameter defined.

REFERENCE(HEADER_CUST_EXP) LIKE HEADER_CUST STRUCTURE

But this structure is really small.

Question: Do I have to extend this structure with my field ablad I need and it should work? Or what can I do to make this work?
