  The SAP error message ICC_CN002, which states "Enter document number range already exists," typically occurs when there is an attempt to create or process a document in a number range that has already been defined in the system. This can happen in various contexts, such as when creating invoices, purchase orders, or other documents that require unique identifiers.
  Cause:
  
  
  Duplicate Number Range: The error indicates that the number range you are trying to use for the document is already defined in the system. This can happen if:
  
  The number range is already assigned to another document type.
  There is an attempt to create a new document with a number that falls within an existing range.

  User Input Error: The user may have mistakenly entered a number range that is already in use.
  
  
  Solution:

  Adjust Document Type Settings:
  
  If the document type is incorrectly configured to use a number range that is already in use, you may need to change the document type settings to use a different number range.
  
  
  
  Use a Different Number:
  
  If you are manually entering a document number, ensure that it does not conflict with existing numbers in the defined range.
