• What is the cause and solution for SAP error message RSDME165 - Source name &1 not in customer name-space ?

  The SAP error message RSDME165 indicates that the source name you are trying to use is not in the customer namespace. This typically occurs when you are attempting to create or modify a data source, InfoObject, or other objects in SAP BW (Business Warehouse) and the name you are using does not conform to the naming conventions or is not recognized as a valid object in the customer namespace.
  Cause:
  
  Incorrect Naming Convention: The name you are using for the source does not follow the naming conventions set for customer namespaces. In SAP, customer namespaces usually start with specific characters (like 'Z' or 'Y') to differentiate them from standard SAP objects.
  Object Not Created: The object you are trying to reference may not have been created or activated in the system.
  Authorization Issues: You may not have the necessary authorizations to access or create objects in the specified namespace.
  
  Solution:
  
  Check Naming Convention: Ensure that the source name you are using starts with the appropriate character for customer namespaces (usually 'Z' or 'Y'). For example, instead of using SOURCE_NAME, use Z_SOURCE_NAME.
  Create the Object: If the object does not exist, create it in the appropriate namespace. Make sure to activate it after creation.
  Verify Authorizations: Check your user authorizations to ensure you have the necessary permissions to create or modify objects in the customer namespace.
  Use Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) to navigate to the relevant area and check the existing objects and their namespaces.
  Consult Documentation: Refer to SAP documentation or your organization's guidelines for naming conventions and object creation processes.
  
  Related Information:
  
  Namespaces: In SAP, namespaces are used to differentiate between standard SAP objects and custom objects created by customers. The standard namespace is reserved for SAP's own objects, while the customer namespace is for user-defined objects.
