3778282 - How to set up default values for the 'Business Partner' and 'Responsible' fields

• Business requirement: Set a default value for the Customer (Business Partner) field and leave the Responsible (Person/Owner) field empty on Service Call create/edit screens
• Despite configuring these defaults in the Screen Configuration app, the behavior does not apply:
  • Customer does not default to the intended Business Partner on either web or mobile
  • Responsible cannot be left blank and is automatically populated
• The issue is consistent across both the web portal and the mobile application
• No error messages are shown; the screens load normally but ignore the configured defaults
• Impact: Users must manually correct the Customer and Responsible fields during creation/edit, increasing effort and risk of inconsistent data
