Anyone know what this means: (Error 1815) cursor must be created with SELECT INTO TABLE?

I am attempting to select from a cursor into a second cursor as the datasource for a report.

Until today it worked. Now I get this strange error message.

Evidently Select is not finding the source cursor -- even though it is the table returned by ALIAS() at the point where the second select commences.

Any ideas would be appreciated.

Regards,
