Assign Letter of Credit Directly in Delivery Order

Dear All,

Business want to assign LC directly into delivery order without assigning it into sales order/contract first. Is it possible to use standard function or do I have to do some enhancement?

Because as per my understanding, LC has to be assigned into sales order/contract first, otherwise the sales order/contract will be incomplete and then we can't create the delivery order.

Please advice.

Thank you.

Best regards,

Anasta
