I am trying to link the back end of my database to SharePoint, but I am getting the error "Certain fields (like 'binary' fields and SharePoint 'read-only' fields) cannot be migrated." The field being affected is called "Created By," and it is a number field with a row source connecting an employee ID to their name. A column for it is created in SharePoint, but it cannot be edited and it changed all the employee IDs in the Created By field to 9 in Access. What is causing this issue? Also, I get multiple "Field values will not be auto-generated" errors, would Access still enforce autonumbering while creating records in the desktop app? If not would I have to use data macros as a workaround?
