This error typically arises in the context of customizing or configuring the SAP system, particularly when dealing with controls in the SAP Fiori or SAP UI5 applications.
  Cause:
  The error occurs when:
  
  You attempt to assign a default control that has already been assigned to another entity or configuration.

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Assignments:
  
  Navigate to the relevant configuration area in SAP where default controls are assigned.

  Remove or Modify Existing Assignment:

  Use a Different Control:
  
  If the control is essential for another configuration, consider using a different control that meets your requirements without causing conflicts.
