What is the syntax to refer project_id in the Project DFF setup

Summary:

When setting up Project Descriptive Flexfield we need to automatically populate one of the DFF segments with value from HR organization setup. In the DFF segment setup we are planning to use initial value sql to get the Hr_organization_v.attribute1.

Ex:

select org.attribute1 from hr_organization_v org, pjf_projects_all prj where prj.carrying_out_organization_id = org.organization_id and prj.project_id = syntax for project_id on the project overview page.
