When a financial dimension is added in Dynamics 365, the new dimension will not be visible in Management Reporter by default.
To add the dimension to the Management Reporter application, there’s a separate setup required in Dynamics 365 General ledger.
Go to Dynamics 365 | General Ledger | Ledger Setup | Financial Reporting setup
Add from the available dimensions to selected dimensions by clicking the right arrow.
The new dimension will be available in Management Reporter after a while. If it doesn’t appear in the MR after a long wait, try resetting the Data mart.
To reset the data mart, Go to Report Designer | Tools | Reset Data mart
