• What is the cause and solution for SAP error message /SAPPO/MSG016 - &1 does not start with Y* or Z* ?

  The SAP error message /SAPPO/MSG016 &1 does not start with Y* or Z* typically indicates that a certain object (like a program, function module, or other development object) does not follow the naming conventions set by your organization or the SAP system. In SAP, custom objects are usually prefixed with "Y" or "Z" to distinguish them from standard SAP objects.
  Cause:
  
  Naming Convention Violation: The object you are trying to create or modify does not start with "Y" or "Z". This is a common practice in SAP to avoid conflicts with standard SAP objects.
  Configuration Settings: The system may have been configured to enforce this naming convention strictly, and any object that does not comply will trigger this error.
  
  Solution:
  
  Rename the Object: If you have control over the object name, rename it to start with "Y" or "Z". For example, if the object is named MY_OBJECT, you could rename it to Y_MY_OBJECT or Z_MY_OBJECT.
  Check Configuration: If you believe the naming convention should allow for other prefixes, check with your SAP Basis or system administrator to see if the naming convention settings can be adjusted.
  Review Development Guidelines: Ensure that you are following the development guidelines set by your organization regarding naming conventions for custom objects.
  
  Related Information:
  
  SAP Naming Conventions: It's a best practice in SAP development to use "Y" or "Z" for custom developments to avoid conflicts with standard SAP objects.
  Transport Requests: If you are working with transport requests, ensure that all objects included in the transport adhere to the naming conventions.
  Development Environment: This error may occur in various development environments, including ABAP development, where naming conventions are strictly enforced.
