SYMPTOM:
Users might notice that they cannot see the option 'Data language' in the Cube Configuration menu, which is a new setting starting from Strategy 10.0 GA. This is specific to the metadata, as by default in Strategy Tutorial MD this option can be seen.
STEPS TO REPRODUCE:
1. Edit any Intelligent Cube.
2. Navigate to Data > Configure Intelligent Cube.
3. Notice Data Languages option is missing.
CAUSE:
“Data language” option in cube might be missing due to the fact that Data Internationalization is disabled for the project. The project might only support one language and it’s no use to display the “Data language” options.
ACTION:
Enable data internationalization by going to Project Configuration > Language > Data and selecting 'Enable data internationalization':

After adding the required languages to the project, the Data Language option can now be seen as expected.
