I have a form with a grid on it. At first I used a cross company AOT query to retrieve data from 5 different datasources, joined to a root table.
This was not performing at al because of authorization matters and the quantity of the data.
My idea was to make the "root" table virtual and place this table in a form as datasource along with the non-virtual datasources I need.
In the executeQuery method of the shared (virtual) table i want to join the other datasources.
Is there a best practice approach for this, or is my thought wrong?
