[Problem Encountered] During the DM synchronization process, an [additional] field was added to the upstream table, but the alter statement was [missing] downstream. This caused the insert statement to not match the downstream structure (missing a field).

Action: I manually added this field to the downstream table to keep it consistent with the upstream.

Issue: Restarting the task still results in the same error. I suspect that the new table structure hasn’t been loaded into DM.
How to handle this???
