We are using SRM 7.0 Extended classic scenario.
Shopping cart is created and approved, but the status is error in transmission. PO in SRM is not created.
I have maintained transaction type in org structure and in sourcing configuration i have maintained 3 sourcing carried out for item without assigned source of supply.
Also when i try to create PO manually in SRM, it is working and replicated to ECC.
Please show some light on this issue.
