In BaanIVc4, we are receiving EDI Sales Schedules from Ford and their monthly requirement dates fall on Sundays. In particular, we have requirements on 6/1/08 and then 6/29/08. When the EDI tries to load, the requirement for 6/29/08 errors out with an error "Date is less than the end date of the Previous Requirement". If I change those two requirement dates to 6/2/08 and 6/30/08, then reload the EDI as monthly, we have no issues and it loads. Any ideas on how to make this work or push the plan period forward to Mondays? Thanks for any help or suggestions.
