Topic: Record Selection How? Posted: 06 Dec 2017 at 6:19am
We are looking at a Crystal report written by someone else and they are selecting records by sending code from another program to Crystal. There is nothing under select records, no added commands, the SQL statement does not select records and no parameter fields are defined in the report.
The report runs from 3rd party program and there are close to 50 input options codded into the 3rd party program.
Just trying to understand how this works. How does Crystal receive this information and know what to do with it?

The report may not be doing the filtering. The application might be gathering the data, filtering it according to the parameters and then setting the datasource of the report in the application...Then all that is left for the report to do is to display the data.
It is the way that i like to write reports as it makes changing databases/servers very simple from a reporting point-of-view.
