Fixed problems in Istanbul Patch 3a

Problem Short description Description Steps to reproduce

Performance Analytics

Refer to the listed Known Error KB article for details.

Service Portal


In Service Portal, catalog item variables are read-only for non-roled users

When the variables in a catalog item have write_roles configured, and a non-roled user tries to create a request using the catalog item, all of the variables are read-only in Service Portal. However, the variables in the catalog item in the normal catalog UI are not read-only.

The Catalog desktop UI checks create_roles when ordering, and it later checks write_roles in the variable editor. However, Service Portal checks write_roles in both places.

The fix for this PRB resulted in an API change to the getCatalogItem method. For details, refer to KB0621849.

  1. As an admin user, navigate to Maintain Items.
  2. Open the Sales Laptop catalog item.
  3. From the related list, open the Additional software requirements variable.
  4. Add the Write roles field to the form if is not already there.
  5. Add the admin role to the variable (so that the admin is required to write to the variable).
  6. Click Update.
  7. Impersonate an ESS user.
  8. Navigate to the Service Portal.
  9. Search for and view the Sales Laptop catalog item.

Expected behavior: Variables are writable in the normal UI and Service Portal.

Actual behavior: Variables are read-only in Service Portal. They are writable only in the normal UI.
