>hi,

I suspect that for running the report, you close the underlying table (the table on which the grid is based).

For example, if you:

use client
set order to "LastName"
report form ClientList...
use

the first command will close whatever table was open in the currently selected work area.

Use the SET command to check what tables where open before, and after, running the report.

To correct the above example, just select a new work area:

use client in 0 && Note the in 0 part - it opens table in the first free work area leaving other tables opened
set order to LastName
report form ClientList...
use

But in general, it is better to work with cursors:

select * from Client;
  order by LastName, FirstName;
  into cursor TempReport
report form ClientList...
use

In this case, the report should have no tables in its DataEnvironment.

HTH,
