How do I update the value of a field programmatically

Question

I want to change a form field "modified_by" to the current sso
user using wwctx_api.get_user before updating the record in the
database, how is a good way to do it? p_session.set_value? not
having much luck with that, I put it in before processesing the
for and get this error when I hit QUERY
Error: An unexpected error occurred: ORA-06502: PL/SQL: numeric
or value error (WWV-16016)
An unexpected error occurred: ORA-06502: PL/SQL: numeric or
value error (WWV-16016)

Hi,
If you create a function to return wwctx_api.get_user you could
call this inside an update trigger, you could put in an
exception to return USER if there is an error, this would then
work for users connected directly and users using Portal.

e.g.
CREATE OR REPLACE FUNCTION F_PORTAL_USER RETURN VARCHAR2 IS
     vRet VARCHAR2(50) := wwctx_api.get_user;
BEGIN
     RETURN(vRet);
EXCEPTION
     WHEN OTHERS THEN
          RETURN (USER);
END F_PORTAL_USER;
