Most common cause of these kind of errors are related to business validations. Those business errors typically not associated with tool itself. Better if you post details like view/lu used to update, migration job’s details / method list etc. Then we have more chance to get the attention of users who have gone through similar experience and solutions.

I was able to figure out what the issue was. There were changes missing in the Source Mapping portions. Default values were missing from the field and causing the error as well as some LU were not correct. Thank you for your response.
