I am trying to upload remittance advice data from a text file. I have created an external file template off the ExtCustPayment file type. When I use the External File Assistant to upload the file, I get an error about Payment Method (Way_Id) cannot be null. It is not null and I can see it has data in the External File Transactions Detail page.

I am not sure if it is just a bad value (thought I did get the value from the dropdown list on the External Payments dropdown for payment type) or if it is not recognizing that there is data in the field.
We are using IFS10.
In case it is needed, here is the File Template build I am using:

I have tried to simplify it down to just the bare bones.
Thanks, Ron
