>but i´ll have use the sys(2015) function in order to create a unique name for the cursor i create

Nope, you could just call it the same name every time, it doesn't matter since you're not creating a file.

>then modify the report's dataenvironment so it open the cursor i created

Nope, leave the DataEnvironment completlely blank, and make sure its not Private. Then, the report will just use whatever is open when its called. ALso, you can leave off any aliases on the report fields and expressions.

>then, after the report is printed, delete the file i created....

Nope, it doesn't create a file on disk, a temporary cursor, to get rid of it, you can simply do "USE".

>Tricky eh?

Nope :-)
