>If I run a report from I form and the form alrealdy has the table in its dataenvironment, must I erase the same table of dataenvironmet of the report ?

Hi Moises,

None of my reports have anything in their dataenvironment. I use SQL to preprare the data exactly the way I want it to look and follow that with the REPORRT command. Also, in my reports I refer to the fields as MyField only, not MyTable.MyField.

If you are running the report from one table and it's already open, all you need to do is make sure it's the current work area. If you had that table in the report's data environment to make it easy to drag-drop fields onto the report, you could take it out of the dataenvironment.
