“The data has been changed” error when stepping from main form into sub form

Question

I\'m migrating an Access database to SQL Server using the SQL Server Migration Assistant (SSMA). The Access application will continue to be used but with linked tables inst

Answer 1

After much trial and error I solved the issue. In the enter event handler for the sub form control on the main form, I requeried the sub form itself.

eg On the main form:

Private Sub Subform1_Enter()
    Me.Subform1.Form.Requery
End Sub

I don't know why this works, only that it does.
