One thing you can do is open the report (use somereport.frx) before the user modifies it. Look for a data environment and if it is not found insert it into the frx (or lbx) file. To see what to insert just add a table to a report data environment in the report designer then "use" the frx file and look for objtype = 25 (data environment) and objtype = 26 (cursor). You also may have to update the CursorSource part of the expr field for the cursor if the path has been changed (such as if you distribute the report with the DE added but the user installs to some other directory).

One rather annoying thing about this however that occurs in the Runtime VFP Environment (but not the Development VFP Environment) is that your users will have to manually open the DE Window before the field list in the expression builder dialog will be populated. There may be a programmatic workaround for this, but I don't know of any (if anyone has one I'd be interested in knowing what it was).

See the file 50frx.dbf in the "Filespec" directory under wherever you installed vfp for more details about frx files.
