SAP Sales and Service Cloud Version 2

1. Log on to the system.
2. Navigate to the Cases list view.
3. Locate the Next Action Review Date column.
4. Click the column header to sort the cases.
5. The screen becomes blank, and the following error message is displayed:
   "An internal server error occurred while running the Search Service."

The custom fields required for sorting were missing from the Search Service index mapping. As a result, the Search Service could not process the sorting request for the Next Action Review Date field.

1. The Search Service index mapping needs to be updated in the backend of the system to include the required custom fields.
2. If you encounter this issue, create an incident with the Search Service development team to request the necessary backend mapping update.
