Had this same problem and none of the solutions here helped me. Hat tip to RBeaghan for this post in another thread:
We had the same error as in your initial post. Epicor Support provided the suggestions below. I have not had the chance to go back and try them yet.
- Make sure that your fields are ordered in the spreadsheet as they would be manually populated via the entry screen.
- The ‘PackLine’ field should be set to “0” (zero), this will tell the system to assign the next number in the internal sequence to the Lines.
- You should include a ‘ReceivedTo’ line, which should be set to “PUR-STK”.
Setting the Pack Line to “0” is what did it for me.
