Dear Srivatsava,
Now I understand better, but I still maintain some doubts:
"you need to create an A2A between your Proxy BO and SupplierInvoice BO"
As I get documentation to perform this part?
I will try to do so by a XBO. I doubt, in that moment I keep XBO in SI BO?
Thanks in advance,
thank you very much for the support,
Regards,
Joe Gonzales.
