If a purchase requisition originates from more than one vendor, then a purchase order will be generated for each vendor. If one or more purchase orders is rejected by BAPI, then the workflow will be directed back to correction of the purchase requisition.

In contrast to the functionality to date, a purchase order is no longer generated if one or more purchase orders contains an error. This is achieved by invoking the BAPI in test mode first. Eliminate all errors from all purchase orders before setting them up with a new invocation in productive mode.
