Inserting Oracle Applications user from custom form to table

 Hi,

I am working on custom form and registering the forms with Oracle apps.

I am using PRE-INSERT trigger to insert created_by and last_updated_by columns in custom table.

Currently, I am using following logic in pre-insert trigger:

CREATED_BY:= USER;

LAST_UPDATED_BY:= USER;

This inserts the database user everytime I create a record.

I would like to insert the oracle applications username instead of database user when creating records using this form in oracle apps-how can this be achieved?
