Not all query datasources available on ListPage

Question

In the MSDN tutorial on adding data sources to a list page, it says

Expand the Data Sources node for the list page. The node includes the query that you added and the data sources associated with that query.

However I noticed not all the datasources of the query for the CustTable list page are available.

Can anyone tell me the criteria for the datasources being available?

Answer 1

DataSources with JoinMode ExistJoin or NotExistJoin are not available.

And make sure that query version on the Data Sources of the list page is same as the query version in the AOT. If not click into Query property and press Enter.
