What is workaround to use Policy agent?

The configured accounting combination may be invalid - If you see the example we provided LD costing used both default and pay element account code made. Can you please check?
The costing hierarchy might be prioritizing a higher-level default : The issue is related to Mapping set issue for LD cost and not actual payroll run

What is the workaround for using the Policy Agent? I tried the recommended option to copy the agent, but the tool remains uneditable.Adding custom tool with company policy document gives message for custom subscription
Do we need additional configuration, or is there a different method or set of steps to achieve this?
