How to map payment methods in Subscription Contract to Provider Contract

[AotoTanokashira]

Hi, community.

I'm a learner of FI-CA module and I have a question about Incoming payment method in Provider Contract.

How can I enter a payment method in the Incoming Payment method field of the Provider Contract?

I have read the following article and believe that the field is automatically mapped from the Subscription Contract.
https://help.sap.com/docs/SAP_S4HANA_ON-PREMISE/95ad0cb1c441447888d695da7f3fd3d9/d1ee7463b49141b1bc3...

Currently, the payment method is entered in the Contract Account associated with the Subscription Contract.

In the Provider Contract settings, "Use Payment Data from Contract Account" field is selected, but the payment method is not entered.

I would like to get your advice on where to customize.

Thank you in advance.
