I am working on a project where I am upsizing an access database to Sql Server. I had very little trouble converting the tables. The application keeps track of requisitions and has a form for entering header information, and a subform that contains information about the line items. Everything works great when viewing existing data. However, when entering a new requisition, the subform does not work when entering information about the line items. It seems like it is not even there. I have tried changing the properties of the form and the subform, examining the related fields, and recreating the forms. It must be something related to the change to SQL server, as it works fine in access.
