The Specified Data Source Could Not Be Found
If when you are running a report or layout in Sage 50 Accounts 2010 from a previous version, you may get the following message:
“The specified data source could not be found. Check that the data source is correctly registered”
If you edit the problem report or layout when the message appears, you will likely either see no variables or tables in the in the variables pane, or in data>Joins, you get the message “Object reference not set to an instance of an object”
All you need to do is reset the data source within the layout or report, you can do this by:
Edit the report or layout>Data>Change Report Data Source>New Data Source>select Sageline50v16>OK>OK
Then File>Save>File>Exit
