2. Click on the Data Management in the workspace.
3. Try to create a job, or select one exiting job and then click on Set Up Import.
4. Perform some transformations and mapping.
5. Continue to click on Next till to Review Import stage.
6. Switch to Dimension Restriction tab.
   => The error message ."Server Error: Failed to fetch restrictions" occurs.

When perform some transformations and mapping, wrongly map a "Date" column to Version, the Version member id should be a "String" column, in the format like "public.xxx".

When perform mapping, changed the Version column type from “Date” to “String” and the issue has been resolved.
