• What is the cause and solution for SAP error message COM_ALTER_IDENT007 - Objects in customer namespace must begin with Y or Z ?

  The SAP error message COM_ALTER_IDENT007 indicates that you are trying to create or modify an object in the customer namespace that does not adhere to the naming conventions required by SAP. In SAP, objects in the customer namespace must begin with either 'Y' or 'Z'. This is a standard practice to differentiate between SAP standard objects and customer-specific objects.
  Cause:
  The error occurs when:
  
  You attempt to create or modify an object (like a table, report, function module, etc.) in the customer namespace (which is typically reserved for custom developments) but do not prefix the object name with 'Y' or 'Z'.
  The object name you are using starts with a character that is not allowed in the customer namespace.
  
  Solution:
  To resolve this error, you should:
  
  
  Rename the Object: Change the name of the object you are trying to create or modify so that it starts with 'Y' or 'Z'. For example, if you were trying to create an object named MY_OBJECT, you could rename it to Y_MY_OBJECT or Z_MY_OBJECT.
  
  
  Check Naming Conventions: Ensure that all custom objects you create in the future follow the naming convention of starting with 'Y' or 'Z'.
  
  
  Review Existing Objects: If you are modifying an existing object that does not follow this convention, you may need to create a new object with the correct naming convention and migrate any necessary logic or data.
  
  
  Related Information:
  
  Customer Namespace: In SAP, the customer namespace is reserved for custom developments to avoid conflicts with standard SAP objects. The customer namespace typically includes all object names that start with 'Y' or 'Z'.
  Transport Requests: When working with custom objects, ensure that they are included in the appropriate transport requests for proper transport between different SAP environments (development, quality assurance, production).
  Development Guidelines: Follow SAP's development guidelines and best practices to ensure that your custom developments are maintainable and do not interfere with standard SAP functionality.
  
  By adhering to these conventions, you can avoid this error and ensure that your custom developments are properly recognized by the SAP system.
