The Audit process validates the tree structure and checks for errors or inconsistencies. If the Audit process fails, you need to correct the errors and run the Audit process again until it succeeds. Then you can set the tree version status to Active. The number of tree versions does not affect the ability to set a tree status to Active, as long as there is at least one tree version defined. Accounting Configuration does not need to be submitted before setting a tree status to Active, as this is a separate task that involves submitting all accounting configuration changes for deployment. Chart of accounts does not need to be deployed before setting a tree status to Active, as this is a separate task that involves deploying flexfield metadata changes for validation and activation.
