Hi,

Are you using a standard configuration or did you modify the standard one?

If you are using a modified one, then I would try to use the standard one in order to see if it is the configuration or another setup.

Seem also, that you need to rebase it if it is a modified one.

I forgot to import the FNO Model Mapping for this GER.

The solution is already outlined in the suggested article: https://www.linkedin.com/pulse/tax-calculation-sten-baumgarten-hud4f/

For more details, I've written some notes.: https://dax365fo.org/2025/11/19/tax-calculaion-no-model-mapping-exists-for-the-legal-entity-data-model/

Thank you @Adis
