SRM 7.0 PO not created in SRM

Hi all,

We are using SRM 7.0 Extended classic scenario.

Process:

Shopping cart is created and approved, but the status is error in transmission. PO in SRM is not created.

Configuration:

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.

Thanks,

Srivatsan
