Here’s a little tip on updating Microsoft Dynamics AX data sources that always seems to slip my mind:
You CANNOT drag and drop a data source into a list page. This is different than most forms, so it always stumps me!
Instead, right click on the ‘Data Sources’ node within the form. The query property sets the data source. If you’ve modified the query and would like to refresh it, you must change the query and then set it back to the query you have modified and want to use.
That’s it! Your data source is now updated and added to the list page.
