PredefineConstraintsInReportSet

#PredefineConstraintsInReportSet

##About

When false, Izenda tries to apply all constraints which it finds in the current schema when generating joined tables SQL. As a result, SQL for the same report can differ depending on external constraints.

When true, at the moment a report is run Izenda generates SQL for joined tables strictly according to constraints listed in the report XML. Note that when saving a report to XML, Izenda writes to the XML all constraints which it finds at that moment in the schema for joined tables.

Default Value: False
