Mismatch in EBP and backend SAP system

Hi Experts,

When checking the status of the shopping carts we have found some shopping carts which has status as "Item in Transfer process" but PO has been created in the backend.

We are running the job for CLEAN_REQREQ_UP every hour and BBP_GET_STATUS_2 once daily.

Some shopping carts get their status updated as soon as they are ordered and follow on documents are created. While for a very few may be 2 or 3 shopping carts has a mismatch between their status.

Can anyone guide about the cycle and the programs which runs after shopping cart is approved, follow on documents are created and the status updated back to EB with follow on document information.

Thanks and Regards

Manoj
