Dear Uli
Thanks for your message, but it seems that this BAPI only used for external key turnover to internal key through test. it couldn't help convert to production order.
actually, we want to find a function module or a BAPI, it could used for conversion planned order to production order in PPDS, then we get the production order number, trigger the interface with non-SAP system.
through debug, we find it always entry in CIF related function automatically, but we don't use standard CIF connection with ECC, so any ideas about this, please propose.
Thanks a lot!
Gruss
Kevin
