Has anyone tested the Payables Agent Policy Details configuration?

Summary:

1. Can someone help me understand the Anomaly Verification sheet in Policy details excel file. I am unable to understand which fields to update and how the logic works. Can anyone please share some use cases that you have tested and succeeded?
2. I have configured Account Coding sheet with distribution combination and distribution set attributes, however, i got some error message stating the value is invalid even though we updated correct target value. Please find the attached file for reference.

It would be really helpful if someone can share some scenarios or example configurations to understand this features better.
Thanks in advance.
