• What is the cause and solution for SAP error message PAK_WB_FOUNDATION302 - Invalid name "&1": Use "/" as a namespace delimiter only ?

  The SAP error message PAK_WB_FOUNDATION302 indicates that there is an issue with the naming convention of an object in the SAP system. Specifically, the error states that the name provided is invalid because it uses a character that is not allowed as a namespace delimiter. In SAP, the forward slash ("/") is used as a namespace delimiter, and its usage is restricted to specific contexts.
  Cause:
  The error typically occurs when:
  
  An object name (like a function module, class, or other development object) is defined incorrectly, using a forward slash ("/") inappropriately.
  The name does not conform to the naming conventions set by SAP, which require that namespaces be properly defined and used.
  
  Solution:
  To resolve this error, you should:
  
  Check the Object Name: Review the name of the object you are trying to create or modify. Ensure that it does not contain any invalid characters, particularly the forward slash ("/") unless it is being used correctly as a namespace delimiter.
  Correct the Naming Convention: If the name is incorrect, modify it to follow the proper naming conventions. For example, if you are creating a custom object, ensure that it starts with a valid namespace (like "Z" or "Y") followed by a valid name without any invalid characters.
  Use Transaction Codes: If you are using transaction codes to create or manage objects, ensure that you are using the correct transaction for the type of object you are working with.
  
  Related Information:
  
  Namespace Conventions: In SAP, custom objects typically use namespaces that start with "Z" or "Y" to differentiate them from standard SAP objects. Ensure that your custom objects follow this convention.
  SAP Documentation: Refer to the SAP Help Portal or the specific documentation for the type of object you are working with for detailed naming conventions and guidelines.
  Development Guidelines: Familiarize yourself with SAP's development guidelines to avoid similar issues in the future.
  
  By following these steps, you should be able to resolve the error and successfully create or modify the object in question.
