Bill Fellows has a script to figure out the name of that table throwing errors upon insertion:
There is a rich set of tables and views available in the SSISDB that operate as a flight recorder for SSIS packages as they execute. Markus Ehrenmüller (t) had a great question in Slack. In short, can you figure out what table is being used as a destination and I took a few minutes to slice through the tables to see if I could find it.
If it’s going to be anywhere, it looks like you can find it in catalog.event_message_context
If someone is using an OLE DB Destination and uses “Table or view” or “Table or View – fast load” settings, the name of the table will be the event message_context table. If they are using a variable name, then it’s going to be trickier.
Read on for the script.
