>In VFP report designer, do I have to fixed a grouping for the report format and design x number of report formats against x number of grouping? Or can I on runtime, change the Report Grouping information?

You can change the grouping expression directly in the frx file:

* Open report frx file as dbf
use YourReport.frx
* Locate the 1st group header
loca for ObjType = 9 and ObjCode = 3
* Change the grouping expression
replace Expr with
* Close the report dbf
use

This is good for the 1st group.

For all other groups you will find the group records in the order you have the groups in your report. So, for the third one, you must issue 2 CONTINUE before changing the expression.

HTH,
