Content (required):

Hello,

I have a requirement to create a Tax book for which the posting are only to the secondary ledger. This Tax book would be used to track goodwill.

What would be your recommended approach to set this up? Is it possible to set up this up with a secondary ledger with data conversion level "adjustment only" and not "Subledger" level?
