• What is the cause and solution for SAP error message TO138 - Object &1 &2 is in reserved name range for SAP partner ?

  The SAP error message TO138 indicates that the object you are trying to create or modify is within a reserved name range for SAP partners. This typically occurs when you are working with objects such as transport requests, function modules, or other development objects that have naming conventions that are restricted to avoid conflicts with SAP's own naming conventions.
  Cause:
  The error occurs because:
  
  The object name you are trying to use falls within a reserved range that is designated for SAP's own use or for specific partner development.
  SAP has defined certain naming conventions to ensure that custom developments do not conflict with standard SAP objects.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Change the Object Name: 
  
  Use a different name for your object that does not fall within the reserved naming range. Typically, SAP reserves certain prefixes or ranges for its own use. For example, custom objects often start with a specific prefix (like Z or Y) to distinguish them from standard SAP objects.
  
  
  
  Check Naming Conventions:
  
  Refer to the SAP documentation or guidelines regarding naming conventions for the specific type of object you are working with. This will help you understand which names are reserved and which are available for use.
  
  
  
  Use a Different Namespace:
  
  If you are working in a development environment that allows for custom namespaces, consider using a custom namespace that is not reserved by SAP.
  
  
  
  Consult with Your SAP Administrator:
  
  If you are unsure about the naming conventions or need further assistance, consult with your SAP Basis or development team. They can provide guidance on the appropriate naming conventions and help you avoid reserved names.
  
  
  
  Related Information:
