Is there any user guide with instructions on how to perform intercompany billing adjustments?

Summary:

Hi All,

Does anyone have a user guide of how to perform intercompany billing adjustments in Projects? We are using the functionality, but there are some options that are different from Billing adjustments. Like reprocess cross charge method, recalculate converted tranfer price amounts (screenshot attached) and we would like to understand each function.

Content (required):

We tried to perform credit memo (invoice cancellation) from Invoice page, but intercompany revenue recognized is not being reversed. Any help is really appreciate it.

From Intercompany Billing tab, we tried to perform some actions but nothing happened. So that´s the reason we would like to understand each function available.
