This is a significant enhancement to our existing data record filter support. Now you have the ability to “stack” data record filters over the same data file. The power this gives you is extensive.
Many times in an application’s logic, data-read requirements might be located in different areas of your code and necessitate different criteria. You might establish one data filter in one location and then later, in another set of logic, find the need for more filtering. Say at logon time, you establish a filter based on user, then somewhere later in the application, a date is introduced.
Now with the ability to “stack” your data file filters, you can add the required filter when you need it most. A new function, SetDataFilterNbr() has been created to use this feature.
