Clarification on "Document Payee Bank Account Number & Document Payee Bank Account ID"

Dear Oracle Payment Manager Guru;

We are in a process of implementing our AP supplier invoice payments with Electronic(EFT) and Wire payment options.

As a part of Oracle Payment Manger supplier bank information we can setup and define User Define validation under our Electronic and Wire payments in Oracle

Payment Manger. I have the following questions:

  1- Do we need to setup both of following Fields under validation section?

      - Document Payee Bank Account Number

      - Document Payee Bank Account ID

2- What is the difference between following 2 fields?

    

       - Document Payee Bank Account Number 

       - Document Payee Bank Account ID
