We have a async scenario ECC
>BI using ABAP Proxy in ECC and BI. Our requirement is to sent Acknowledgement back to ECC once the processing is complete in BI. We see the Acknowledgements coming in PI from BI, but we are unable to send it back to ECC, so in ECC in SXMB_MONI it shows as waiting for Acknowledgement. In PI SXMB_MONI, I do see the Acknowledgements.
Could you please advise what addional setting do I need to do in PI/ECC to send the Acknowledge from PI to ECC.
