Deffered property and Automatic Query?

If Deffered property is set to ‘NO’, associated detail records are retrieved immediately after master record retrieval.

If Deffered property is set to ‘YES’ & Automatic query property is set to ‘YES’, associated detail records are retrieved when the form cursor is position on detail block.

If Deffered property is set to ‘YES’ & Automatic query property is set to ‘NO’, associated detail records will not be retrieved. An explicit execute_query must be executed for corresponding details records.

By default Deffered property is set to ‘NO’ & Automatic query property is set to ‘YES’.
