PaymentNumber auto assigned by sequence when using rest api to create payment

Summary:

When creating a payment via rest api, i need "PaymentNumber" to be auto assigned by fusion.

(otherwise, this forces our middleware to maintain a sequence from the outside, and the business doesnt like it)

Content (required):

When creating a payment using the rest api : https://docs.oracle.com/en/cloud/saas/financials/23b/farfa/op-payablespayments-post.html , fusion asks for the variable "PaymentNumber" which description is : "The check number printed on physical check."

This field is mandatory as, I I dont provide it, I get the error message : You must provide a value for the Payment Number attribute to perform this operation. (AP-810787)
