Hi Kevin,

This time I got another error message when try to update the record using business object. I select the record from more than one table and load the record into the page.
When the save() function as below is called, the error occurs.

If Me.Save(Me.oVxlve, dsVxlve, Me.oVxlve.TableName) = mmSaveDataResult.RulesPassed Then
     Response.Redirect("ViewRecords.aspx")
End If

The error message as below:

Dynamic SQL generation is not supported against multiple base tables. 
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.InvalidOperationException: Dynamic SQL generation is not supported against multiple base tables.

What is the cause of this error?
