  SAP Error Message WA168
  Message Text:
  
  & is in customer namespace
  
  Cause
  
  The error message WA168 occurs when an object (such as a program, function module, class, or any repository object) is created or referenced with a name that starts with the letter Y or Z.
  In SAP, the namespaces starting with Y and Z are reserved exclusively for customer-specific developments.
  This message is a warning or informational message indicating that the object is in the customer namespace.
  It is not an error in the strict sense but a notification to ensure that the object is recognized as a custom development and not part of the SAP standard.
  
  
  Explanation
  
  SAP standard objects use namespaces other than Y and Z.
  Customer developments must use names starting with Y or Z to avoid conflicts with SAP standard objects.
  This message helps developers and administrators identify that the object is custom and should be handled accordingly (e.g., during upgrades or transports).
  
  
  Solution / Recommended Action
  
  No correction needed if the object is indeed a customer development.
  
  The message is just informational.
  Ensure that all custom developments use the Y or Z namespace to avoid conflicts with SAP standard objects.
  If you see this message unexpectedly (e.g., for an object that should be standard), verify the naming conventions and correct the object name if necessary.
  During transports or upgrades, be aware that objects in the customer namespace are custom and may require special handling.

  SAP Namespace Concept:
  
  SAP reserves namespaces to avoid naming conflicts.  
  
  Standard SAP objects: Namespaces other than Y and Z.  
  Customer objects: Namespaces starting with Y or Z.
  
  
  
  Transport Management:
  
  Objects in the customer namespace are transported differently and should be carefully managed during system upgrades.
  
  
  Development Guidelines:
  
  Always start custom object names with Y or Z to comply with SAP naming conventions.
  
  
  SAP Note / Documentation:
