Hi experts,
Sorry for delay, but I solved this issue.The problem was more simple that we imagine...
The language in ECC x PI X SRM were differrents.
ECC was 'EN'.
PI was 'DE'
SRM was 'EN'
For this, when the PI called SRM, no found the product because he tried with the own language (DE).
Solved this problem setting the same language in all systems.
Kind Regards,
Dhan
