Questions on Project Accounting information usage on AR Transactions DFF

Hello Experts,

I have a query on Project Accounting. We are trying capture project related information on AR Invoices by using DFF on Transactions form. Due to various business reasons users enters the Project related Invoices in AR Transaction form directly without being routed it through Project Accounting. In this case, we have enabled DFF at AR Transaction form to capture Project Information.

Here I have enabled below fields

1. Project Number

2. Task Number

3. Organization

However, we also need to add Task Type, Task Description and Project Name fields to the DFF. I tried to get the value set for these fields but could not locate them exactly. Can you please help me to this configuration done.
