>Prior to running my report I have the tables needed already open and the table that "drives" the report selected and positioned to top. In the data environment object I have autoopentables and autoclosetables set to .f. , and the initialselectedalias property set to the alias of the open file. Yet, the report engine still prompts for an input file. How can I get the report to use the open files.

In addtion to what Hilmar said, make sure that Private Data Session on the Report menu isn't checked.
