Thank you Phani,
i did all this steps but it is still not working, i mean, everything works fine but it seems like the code is not called when i do it from bw.
when I test the datasource in rsa3 it works perfectly, i debugged step by step and the code works right, my zzfield is filled correctly.
in bw, I deleted the datasource and replicated metadata again, i created and executed a new infopackage. everything seems to be right, i have no errors, but when i check the psa data my zzfield is always empty. it looks like the code is not executing.
any other idea?
Thanks
Serge
