When using the excel add in a user is updating a value they have permissions to. In turn this should trigger a notification, This has worked for this user before. However the excel add-in now gives the error:
Cannot insert the value NULL into column 'User_ID'. table 'MasterDataServices.mdm.tblNotificationUsers': column does not allow nulls. INSERT fails.
the user exists in the database but I cannot find out why this occurs. any ideas?
