Howto use the Payment guarantee/ Financial document for domestic customer

Hi Experts,

Seasons Greeting.

My Requirement is that

The Customer is the domestic. Customer will provide the Bank Guarantee. The Bank Guarantee will have start date and end date. The customer can submit the Bank Guarantee to one and only one institute/organization. It means the Bank Guarantee document will be in physical possession of that institute/organization. Using Bank Guarantee the financial institute gives the assurance of the payment agreed into the Bank Guarantee. This Means that bank will honor the payment if customer fails to pay and the company/organization decides to revoke this financial document within the validity period

I am wondering whether I can achieve this using the SAP Documentary payment. But per sap documentation provided on help.sap.com its used for Export scenarios

Appreciate your views on this.

Thanks and Regards
