Query Background Processing Buttons
Use this button for background processing of queries.
The Query_RunInBackground button
configured in the
special headers Query and QueryFooter in UPDATE_DEFAULT
allows the background processing of queries by CRM.server. For further details, see Background Queries.
Once the query results are retrieved and stored as a query snapshot, the user is notified with a message that his query results are available.

Analogous, the Query_RunInBackground_CSV button
allows the background creation of a CSV file containing the query results. CRM.server creates a D1 document that is linked (via a D3-link) to the message the user receives upon completion.
To allow users to directly create a CSV file with the query results, you need to configure
the Query_RunInBackground_CSV button into the Query
and/or QueryFooter header(s).
