How to check the mapping between costing and revenue in Oracle fushion

Hello,

Please guide me on how to check the mapping between Costing and Revenuw in Oracle fushion.

The current settings are as below

However, I got this from my users. I cannot check the settings for CR. Return of goods (cost porttion) - actual and DR. Return of goods (revenue portion) - actual if they are correct by myself because I do not know what tasks manage these.

I appreciate your support.

Thanks!
