I'm experiencing some odd behavior with an SSIS package I created.
It's using a basic LOOKUP component to check for a preexisting record. If it finds the record, it skips over it and moves onto the next one. If it doesn't find the record, it performs an insert. The lookup is on one column: ESTIMATE_ID.
What has now suddenly happened is the lookup is now trying to insert a record where the ESTIMATE_ID already exists in the target table.
This is just odd because everything has been running fine for literally over a year and now all of a sudden....!
If anyone has seen behavior like this in the past, please feel free to provide any insight you may have.
Thank you!!
