• What is the cause and solution for SAP error message PAK_WB_FOUNDATION305 - Invalid name: "&1" consists of the namespace prefix only ?

  The SAP error message PAK_WB_FOUNDATION305 indicates that there is an issue with a name that consists solely of a namespace prefix without a valid object name. This typically occurs in the context of SAP's development environment, particularly when working with ABAP or other development objects.
  Cause:
  The error arises when you attempt to create or reference an object (like a class, function module, or other development artifacts) using a name that is not valid. Specifically, the name you provided consists only of the namespace prefix (e.g., Z_ or Y_) without any additional identifier. In SAP, object names must follow specific naming conventions, and a valid name must include both the namespace and a meaningful identifier.
  Solution:
  To resolve this error, you should:
  
  
  Check the Object Name: Ensure that the name you are trying to use includes both the namespace prefix and a valid identifier. For example, instead of just Z_, use something like Z_MY_OBJECT.
  
  
  Follow Naming Conventions: Make sure that the name adheres to SAP's naming conventions. Typically, this means:
  
  The name should start with a namespace (like Z_ or Y_).
  It should be followed by a meaningful name that describes the object.
  Avoid using special characters or spaces.
  
  
  
  Modify the Name: If you have control over the naming, modify the name to include a valid identifier. For example, if you intended to create a class, you might change Z_ to Z_MY_CLASS.
  
  
  Check for Typos: Ensure there are no typographical errors in the name you are using.
  
  
  Consult Documentation: If you are unsure about the naming conventions or the specific requirements for the object you are trying to create, refer to the SAP documentation or guidelines for naming conventions.
  
  
  Related Information:
  
  Namespace Prefix: In SAP, custom objects are typically prefixed with Z_ or Y_ to distinguish them from standard SAP objects.
  Development Environment: This error is often encountered in the ABAP Workbench or when using transaction codes related to development (like SE80, SE11, etc.).
  SAP Notes: If the issue persists or if you encounter additional errors, consider checking SAP Notes or the SAP Community for similar issues and solutions.
  
  By ensuring that your object names are valid and follow the required conventions, you should be able to resolve the PAK_WB_FOUNDATION305 error.
