Hello Hubery,
Below is my understanding,
- Sender System is ECC and Receiver is a third Party System.
- The Data you want to send to the third Party system is present such that a few fields are in DEMBAS and a few fields are replicated in ADRMAS. Is this correct?
If that is the case, then you would need to have a BPM in your PI to get the data from both these IDoc's and then combine these into a single file. The BPM will use the Customer ID as the Correlation Field.
If you are certain that the fields are being displayed only in ADRMAS and not in DEMBAS in the runtime and if you want to avoid a customization in SAP..
