CAUSE

The above error indicates that the SQL procedure DB2INST1.SELECTROW failed with SQL1224 because during its execution, a LOAD command using the LOCK WITH FORCE option was issued against the same table that is referenced in the stored procedure. The LOCK WITH FORCE option allows the load command to force off other applications that hold conflicting locks on the target table.

SOLUTION

Execute the SQL stored procedure after the load is complete.
