• What is the cause and solution for SAP error message CNV004 - Use the namespace for customer packages: 90000 - 99000 ?

  The SAP error message CNV004, which states "Use the namespace for customer packages: 90000 - 99000," typically occurs when you are trying to create or modify a package in the SAP system that does not fall within the designated range for customer namespaces. In SAP, namespaces are used to differentiate between standard SAP objects and customer-specific objects.
  Cause:
  
  Incorrect Package Namespace: The package you are trying to create or modify is using a namespace that is not allowed for customer development. SAP reserves certain namespaces for its own use, and customer packages should be created within the range of 90000 to 99000.
  Development Class: If you are trying to create a development class (package) outside of the specified range, the system will throw this error.
  
  Solution:
  
  
  Create a Package in the Correct Namespace:
  
  When creating a new package, ensure that you specify a package name that falls within the range of 90000 to 99000.
  You can do this by navigating to the transaction code SE80 (Object Navigator) or SE21 (Package Builder) and creating a new package with a name that adheres to the customer namespace rules.
  
  
  
  Check Existing Packages:
  
  If you are modifying an existing package, check its namespace. If it is outside the allowed range, you may need to create a new package within the correct range and move your objects to this new package.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or guidelines regarding naming conventions and namespaces to ensure compliance with best practices.
  
  
  
  Related Information:
  
  Namespaces in SAP: SAP uses namespaces to manage and organize development objects. The standard SAP namespace is typically from 0 to 89999, while customer namespaces are from 90000 to 99000.
  Transaction Codes:
  
  SE80: Object Navigator, where you can create and manage packages.
