206 Error in 7.23 UC6 on HP-UX 10.2

Hi Is there any work around for the problem ? Problem : When I ran a 4GL [4GL version 4.11 ] program on 7.10 IDS it was working fine. But when I ported to 4GL 6.X on 7.23 UC6, it is not working. All it does is, calls a stored procedure[ on an external database] inside a 4GL program. The stored procedure insert values into a child table which has a foreign key referencing a parent table. Necessary triggers for establishing this referential integrity are created using ERWin. I get an error 206 : Table [Parent table] not found. even though the database contains the table. If I run the same stored procedure through DB access, it goes through fine. Please let me know if you had encountered problems like this . TIA, Hari
