Are you connecting to an SAP S4 HANA system by any chance?
Also, what version of PowerCenter are you using?
yes, the system is SAP S4 HANA.
The PowerCenter Version is 10.2.0 HotFix 2
Maybe you can ask the same in the PowerExchange Adapters forum if this is related to PWX for SAP.
FYI- I have moved this to the PWX adapters queue.
You are most likely running into a known issue.
Please open a case with Informatica to further isolate the issue and see if this requires a fix or other solution.
Could you please send us the screenshot of how the input parameters looks at SAP side?
the problem is solved. It turns out that this is a known problem and there is an emergency fix to it, which includes additional SAP transport. After installing it, it all works fine.
Unfortunately the transport was not part of the PowerExchange package.
Thank you all for the support.
