I tried to publish the records from my INT database (DB2) to Target DB(TDM repo).I am getting the below error.
But previously(2 months back) when i validate the function in my data maker it worked well and i was able to publish with the same function.
This looks like a data or a query issue.
Here are some details about this error code from IBM:

Maybe check with the DBA to ensure that object exists accordingly.
