Within the report function, 4GL generated an SQL statement to save rows into a temporary table. The dynamic preparation of the statement (see the reference material on the PREPARE statement) produced an error. Probably the database tables are not defined now, at execution time, as they were when the program was compiled. Either the database has been changed, or the program has selected a different database than the one that was current during compilation. Possibly the database administrator has revoked SELECT privilege from you for one or more of the tables that the report uses. Look for other error messages that might give more details.
