Use Parameter to choose Group and Sort options

Question

I've got a report that gets used for several different puposes, and needs to be grouped or sorted differently each time.  How can I use a parameter to let the user choose the group and sort options at runtime?
I'm using CR2008, and SAP B1 2005.  The various grouping options I want to offer include SKU, Vendor and Description, and sorting within those Groups by SKU or Description.
I'm a newbie with CR, so detailed instructions would be really helpful.

You can create a report using parameter field. Follow these steps
-- Create new parameter in the field explorer window
-- The parameter shouls be static and enter all the field names on which you want to create in the values option
-- Now create a formula like this
if {?Parameter}="fieldname1" then
else
if {?Parameter}="fieldname2" then
else
-- Now insert new group and select this formula
-- Now the group will change according to the parameter selected
Please note that if you have different data types of fields you must need to convert totext()
as If condition will allow only one data type output.
Also when you insert any group by default the data is sorted on grouped field. If you want to sort on another field then you need to insert a summary field on that and go to report>group sort expert>select the field-->All based on the summary inserted.
Hope this helps!
