Access to GL Field Status Group Settings

In 4.0B, transaction FS03 - Display GL Account, I enter an account number and a company code and hit enter. On the next screen, I hit the Next Screen Button(F8). Near the bottom on the screen is field 'Field Status Group'.

Now use menu path EXTRAS-->Field Status Screen. I get a list of groups and I double click on group 'Payment transactions'.

The second field on the next screen is called 'Value date' and it has radio button 'Req.Entry' set.

From looking at the F1 help on 'Field Status Group', it mentions that 'The field status when you create a document also depends on the posting key'.

So now my question. Given that I have the account number, company code and posting key, how can I retrieve the data that tells me that 'Value date' is a required entry from my ABAP program?
