Hi,

Probably random infrastructure issue (Vertica cluster error), in most cases those should disappear after loading DM again. If not usually way to go is to create ticket with Celonis and put that error ID, if it's really related to infrastructure, you cannot do much about it.

This can also be the case if you have dropped and recreated the tabel you just need to make the connection again in the Data Model and load again.
