Issue with foreign key not updating while using write to data store entity

Question : I have a @onetoone xsd that creates 2 cdts(Request, FRM003). In my process model(write to data store entity) it inserts a new record to both tables, but the FRM003 table does not update the foreign key of the requestID which is the primary key of the Request table

INTEXP_Request_FRM.xsd
