I have a report that shows a master record and need to show several line details form 2 different tables. If I use joins and groups then the data repeats. I added a subreport to show the details from table 2 while table one is the detail of master (group table) . Report takes long time to populate the subreport linked with invoice id (Subreport is a SQL command) What can I do to make it faster?
Master table invoce
Subreport Invoice 10001
