Hi @ynwkm ,

The error message points out the the problem is related to column PART_NO
How has you setup the migration job?

Firstly create the header and press save
If you have filled in a value in the view name in the header section the fields based on the view should be generated

It is not possible to create header and file mapping at the same step

So please do following:
Only create the header and save
Afterwards you can handle the file mapping section

Hello, thank you for your response.
You were right - I had to fill in the Header and Formatting details, then move onto the File Mapping tab.
Thank you!
