• What is the cause and solution for SAP error message RSO823 - Enter a customer development class (&1 belongs to SAP) ?

  The SAP error message RSO823, which states "Enter a customer development class (&1 belongs to SAP)," typically occurs when you are trying to create or modify an object in the SAP system, and the system is expecting you to specify a customer development class instead of a standard SAP development class.
  Cause:
  
  Development Class Requirement: The system is designed to ensure that custom developments are stored in customer-specific development classes rather than in standard SAP development classes. This is to prevent modifications to standard SAP objects, which can lead to issues during upgrades or support pack installations.
  Incorrect Development Class: You may have inadvertently selected a development class that is part of the SAP namespace (e.g., SAP, SAP_, etc.) instead of a customer namespace (e.g., Z* or Y*).
  
  Solution:
  
  Select a Customer Development Class: When prompted for a development class, ensure that you enter a valid customer development class that starts with Z or Y. If you do not have a customer development class, you may need to create one.
  Create a New Development Class:
  
  Go to transaction code SE80 (Object Navigator).
  Select "Development Class" from the dropdown.
  Click on the "Create" button.
  Enter a name for your new development class (it should start with Z or Y).
  Fill in the required fields and save your new development class.
  
  
  Use the Correct Namespace: Always ensure that any new objects you create are assigned to a customer namespace to avoid this error in the future.
  
  Related Information:
  
  Development Classes: In SAP, development classes (also known as packages) are used to group related objects together. They help in organizing the development work and managing transport requests.
  Transport Management: Objects in customer development classes can be transported between different SAP systems (e.g., from development to production) without affecting standard SAP objects.
  Namespace Conventions: SAP uses specific naming conventions for development classes. Customer development classes should always start with Z or Y to differentiate them from standard SAP classes.
  
  If you continue to experience issues or if the error persists after following these steps, it may be helpful to consult with your SAP Basis or development team for further assistance.
