SQL Loader Error

I am getting the following error when using the SQL loader:

SQL*Loader-926: OCI error while executing delete/truncate (due to REPLACE/TRUNCATE keyword) for table "SCOTT"."SOURCE"
ORA-02292: integrity constraint (SCOTT.FK_ORD_SOURCE) violated - child record found.

In the control file I am loading data with the REPLACE option.

Please explain.

Sql*loader can not delete your existing records before loading new ones because you have existing records in child-related table. Either disable that constraint FK_ORD_SOURCE or remove all rows from that child table.
