Hi Gurus,
I've an asynch integration 3rd party (file) --> PO 7.3 --> SAP ECC (Custom Z Idoc).
I need to send an application acknowledge from ECC to 3rd party using a new custom interface and I think that using ALEAUD on ECC side could be a nice approach.
My planned ack scenario should be SAP ECC (ALEAUD generated from RBDSTATE) --> PO --> 3rd party (file).
Our 3rd party application has a unique Id (called mdoc) wich is needed to send on our ack. My problem is that in outbound ALEAUD idoc generated from SAP, E1STATE-DOCNUM is not populated with mdoc. (i'm filling EDIDC40-DOCNUM with mdoc value on Message Mapping).
Does anyone know how SAP is filling E1STATE-DOCNUM (i think from srel) and what configuration steps are needed to store original document number?
Thanks in advance!!
