In a Dynamic Report or Custom Report (or any report using a DBRW), when using an Action Button to navigate to another sheet, I can capture a dimension element of the active / selected cell containing a DBRW and pass it to another sheet using the "Selected DBRW" option of the "Advanced options" for the Action Button. This is very useful when, for example, I need to grab the GL account from the selected row in the source sheet and pass it to the target sheet.
Since Universal Reports don't use DBRWs, how can that functionality be replicated with a UR?
