How to use Specify Skip Rule in PPM Workflow?

Summary:

We are encountering an issue with the "ApproveAdjustment" workflow in PPM, where cost transfers are being auto-approved even after they are explicitly rejected by approvers.

After testing and analysis, we identified that the behavior is caused by the PPM Negative rule, which is automatically approving the transaction from other workflow stages which this transaction is not intended to enter (red-boxed). Based on our design, it should route to the correct workflow stage where the approval conditions are evaluated per Organization.

We are currently exploring the Specify Skip Rule as a possible solution to prevent the transaction from entering the unintended workflow stage. However, we have not been able to find sufficient documentation, references, or sample configurations that clearly explain how to correctly use Specify Skip Rules in this scenario.
