  3. Search and open Ticket LMN (where LMN is the ticket id) of type T1 (where T1 represent ticket type).
  4. You can see ticket LMN is having the Service Category with value as XYZ (where XYZ represent service category name).
  5. The ticket LMN is created for the Catalog CA1(where CA1 represents catalog id )
  6. Go to the Related Items facet .
  7. Click on the More option and click on Create Ticket.
  8. In this new follow-up ticket screen, change the ticket type from T1 to T2 (where T2 represent another ticket type).
  9. You get an error as Please enter another service category. XYZ is not valid.
  10. Also when you click on value help of service category field in this follow-up ticket screen, you could not see service category value as XYZ.


  1. Go to the Administrator work center.
  2. Go to the Service and Social view.
  3. Click on the hyperlink Service Categories and open the Catalog Id as CA1.
  4. Click on the View All button, in the General facet under an Usage the Ticket Type as T2 is not added.
