Hi
You could copy the outbound process code for ORDRSP to you own one (Transaction WE41). Then change the processing mode from 'Processing with ALE service' to 'Processing with trigger (inbound)'.
Then maintain the partner profile to send the ORDRSP IDOC to your own logical system. The result will be that the outbound IDOC will be returned to your system as an inbound IDOC.
Then for the inbound ORDRSP IDOC maintain process code ED08 in the partner profile (Transaction WE42). The result will be that the ORDRSP IDOC will be distributed as an outbound IDOC to all ALE systems in the distribution model. When you maintain both the PI and Webmethods system in the distribution model then the IDOC will be distributed to both systems.
