How PA Invoice date would be defaulted while release?

Hi,

After generation of "Invoice Date' would defaults while release 1) Normal external customer Projects Invoices 2) PA Internal (Intercompany Invoices), in PA Invoice Review form, upon Click 'Release'.

Note: In my case, I am generating Invoice and revenue based on Work.

Below three actions completed on 03-SEP

1. Revenue generation program run completed.

2. Generation draft Invoice program completed.

3. Generation Intercompany Invoices program completed.

Below actions performed on 04-SEP.

5. Approved both above Invoices

6. Click 'Release' then window open to allow to enter 'Invoice Date' However,

               6.1. For Normal Project Invoices this date populates as 03-SEP

               6.2. For PA Internal Intercompany Invoices this date populates as 04-SEP by default
