Message Duplication in Integration Engine

[Former Member]

Dear all,

We have issue in one of our PI Production Servers.

It is an inbound interface, Idoc flat files are being picked up by PI and are converted into proper SAP Idocs by ABAP Mapping.

In this case, messages are getting duplicated and SAP Idocs of previous messages are getting copied in the subsequent messages.

In the duplicated messages, we have observed that,

1. In SXMB_MONI, some pipeline steps are not getting displayed when compared to the successful messages.

Successful Message, Pipeline Steps

Inbound Message ( CENTRAL )

Request Message Mapping

Response

The converted message is having multiple entries of <?xml version="1.0" encoding="UTF-8" ?>

Will this help out in tracing the issue.

Regards,

Younus

Hi Younus,

>The converted message is having multiple entries of <?xml version="1.0" encoding="UTF-8" ?>

Please compare the messages at step "Inbound" and "Request Message Mapping": Does the double entry appear at Mapping Runtime?

If yes, you should [debug your ABAP mapping|https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/2465] [original link is broken] [original link is broken] [original link is broken];.

hi Younus Mohd ,

the tool itself does not duplicate messages. you should chech 2 thing.

1) if the flat file is not greater than 1000 segments

2) test your abap mapping in a dev enviromentto check why the mapping fails with the file.

Thanks
