I'm working on a project where we need to send 2 years worth of X12 852 Activity data. The data is sourced from NetSuite and needs to be grouped by weeks. I've got a presave page script creating records in a single page with one record for each week.
I tried using option to generate one file per key and set the groupKey value to the week number in the record data.
I'm getting this error : Outbound aggregation is not supported for this EDI document type. Unable to derive groupKey from file definition.
I can't find any documentation on this feature. Is it possibly to generate a file for each record in a page rather than one file per page of records?? How do I set that up if so??
