Payment Block for open items in F-53 or F-58?

[former_member284465]

Hi Experts,

Here I have a scenario, Is there any way to mark all open items for vendor as a payment block in manual payments i.e. in F-53 or F-58? I have maintained Payment Block *B* in vendor master and for the future invoice Payment block *B* is maintaining but I want to restrict all the open invoices that have been posted before a Payment Block.

Further, If any one can suggest me any User Exit or Validation to cater this scenario that will be helpful.

Thanks!

Regards,
