I have seen lot of messages posted in SDN related this issue , but no where i could get the solution to resolve this issue.
In BBP_PD , The shopping cart remains in 'Approved' status and does not come across any errors .No purchase order is created in back end system.
I have debugged the complete shopping cart approval process and its related workflows.
During debugging, i confirmed that the system is deriving the back end object to be created as purchase order and does validations and no errors found. Only thing i could not see is try creating a purchase order.
We are using SRM 7.0 and back end system is 6.0.
Please let me know what;s wrong with the systems. Also to highlight that this is the case only with a few shopping carts and the rest are working fine i.e. creating POs once they are approved.
