Hello Nikhil,
Java IDoc adapter in release 7.4 supports dynamic queue name determination - it actually recognizes queue name of a received IDoc and re-uses it when assigning serialization context for corresponding processed PI message. Having this in mind, please:
- In sender system which is producing IDocs, enable IDoc serialization and create queue names based on document number. For example, in SAP ABAP systems, enable queue processing for respective message type in partner profile (tx. WE20) and specify queue rule name that generates queue name following required logic - based on document number (tx. WE85). Queue name generation shall be implemented in a function module (assigned to a queue rule name in tx. WE85) - there, you can retrieve document number from the processed IDoc and use it when forming a queue name. More details can be found at Queue Name Rules - IDoc Interface/ALE - SAP Library;
- In Java IDoc sender communication channel, enable EOIO mode. You will need to provide a fixed queue name in channel configuration after you enable EOIO mode, but in PI/PO 7.31 / 7.4 this queue name is overwritten by queue name of the received IDoc (the one set by a sender system when processing the IDoc).
Regards,
Vadim
