Hi everyone,
Has anyone successfully worked with the Tax Calculation Engine in Central Invoice Management (CIM)?
One of our clients recently faced issues with how taxes are handled in CIM. While the Tax Code is determined correctly, there’s no automatic verification of whether the tax amount on the invoice is accurate. So we were excited when SAP released the "Verify Tax" feature — but now we’re trying to understand how it actually works.
A few key questions I’m hoping someone here can clarify:
How does the "Verify Tax" functionality work in detail?
We are using S/4HANA Public Cloud as our backend — is the Tax Calculation Engine compatible with that?
Why is it mandatory to manually maintain shipping information for tax determination? This is a cumbersome process and not very user-friendly.
The documentation for this feature and related APIs is quite limited. For example, what exactly is the role of the "APIs for Internal Tax Engine" mentioned in the SAP Help Portal?
From an end-user perspective — how are they supposed to manage or interact with this?
Would appreciate any insights, best practices, or real-world experience anyone can share!
Thanks and best regards,
Sergen
