SFS claim settlement: Wrong due days updating into FI(FB03) from CRM

Hi Team,

I have an issue like below.

I am creating a SFS claim from CRM web UI where the Customer(main account on which the claim is creating) is having

payment terms SF30(due days 30) and remit account(vendor) to which the actual amount should get credited is having

payment terms as PNIR(due days ZERO).

Now when we create billing document in CRM/accounting document in FI(both will get creating immediately when we process the claim  from tcode "/BEA/CRMB01") the accounting document in FB03 showing the payment term as PNIR(which is correct as per user) but due days is populating as 30 which is wrong and the correct one should be ZERO according to PNIR payment term.

PS:Payment terms is populating correctly but due days are wrongly populating.

Please help here.

Thanks.
