Hello , We are facing one problem in forecast seeded form MRPFFDIF.fmb There are 2 fields Bucket and Date , Bucket field has the lists 'Days', 'Weeks' And 'Periods'. If we select Bucket as Days , the calender in the date field allows to select all dates. If we select Bucket as Periods , the calender in the date fields allows to select only few dates . Remaining dates has been disables . Could you please help me to find the Logic behind this .
