  The SAP error message CTE_FND106 indicates that the logical system name you are trying to use is already in use by another system in the SAP landscape. Logical system names are unique identifiers for different systems (like development, testing, and production) within an SAP environment, and they must not be duplicated.

  Duplicate Logical System Name: The logical system name you are trying to create or modify is already assigned to another system in the SAP landscape.
  Configuration Error: There may be a misconfiguration in the system settings where the logical system names are not properly managed.

  Delete or Modify Existing Logical System:
