No problem at all, on the contrary, it is very important to know what we have to improve.

Everything ok,
I apologize if lately I insert several posts,
but working with another report editor where certain features are conceptually different from those of Valentuna Studio, I have some problems in recreating the same report template.

Actually, there is a workaround.
If you define the source query like:
SELECT *, $P!(pGroupBy=field1) AS groupingField FROM table1

And add grouping for groupingField

It is possible to change pGroupBy parameter to different values in the runtime.

yes, in some projects I use this feature with "CR....L RE....S"

Hello,

No, it's not possible. Do you know another report editor which is able to do it?
