ESI Transaction Failure

[SS_10607365]

I am using Windchill Enterprise Systems Integration Release 12.1 and Datecode with CPS 12.1.2.16

ESI Integration transaction status shows Failed and not generating Payload xml

Here are the errors that I faced
An error occurred while generating the ESI response. See the error logs for more information. Error message: The selected object "XXX" has not changed since it was last successfully published.

This is Windchill's standard operation when the system checks the data to be sent against the last successfully sent version.

If it finds no differences, it does not execute and write anything.

Take a look also to this article

Publishing object failed with error: "xxxxx" has not changed since it was last successfully published in Windchill Enterprise Systems Integration

This is expected you can't send same stuff twice to ERP ,try to revise the object and give a try
