VI IMport Serial # in Use

Importing and Serial Number in source file indicates already in use

1) Check IML to make sure they are on supported version.

2) Have them navigate to the IM404_TransactionTierDist file and note the Transaction Entry number.

3) Next check the IM_TransactionHeader and IM_TransactionDetail to see if the transaction number exists there. 

4) If it does, then chances are there's a valid entry in Transaction Entry for that serial number

5) If not, have him delete the record from IM404_TransactionTierDist, then Re-initialize the IM404_TransactionTierDist file only and try the import again.

It could have been that the VI job created an orphaned record in that file.
