• What is the cause and solution for SAP error message PAK163 - Package &1 must not use any objects from its superpackage &2 ?

  The SAP error message PAK163 indicates that a package (let's call it Package A) is trying to use objects from its superpackage (Package B), which is not allowed in the SAP system. This restriction is in place to maintain a clear hierarchy and organization of packages, ensuring that dependencies are managed correctly and that the integrity of the package structure is maintained.
  Cause:
  The error occurs when:
  
  Package A is defined as a subpackage of Package B.
  Objects (like classes, function modules, or other repository objects) in Package A are referencing or using objects from Package B.
  
  Solution:
  To resolve this error, you can take one of the following actions:
  
  
  Remove Dependencies: 
  
  Check the objects in Package A that are referencing objects from Package B. You will need to modify these objects to remove the dependency on Package B. This may involve:
  
  Redefining the logic to avoid using objects from the superpackage.
  Creating new objects in Package A that replicate the necessary functionality without referencing Package B.
  
  
  
  
  
  Reorganize Packages:
  
  If the dependency is necessary and cannot be removed, consider reorganizing your package structure. You might:
  
  Move the dependent objects from Package A to Package B if it makes sense from a design perspective.
  Change the hierarchy so that Package A does not depend on Package B.
  
  
  
  
  
  Check Package Attributes:
  
  Ensure that the attributes of the packages are correctly set. Sometimes, the package settings might need to be reviewed to ensure that they align with your intended design.
  
  
  
  Related Information:
  
  Package Hierarchy: Understanding the package hierarchy in SAP is crucial. Packages can have subpackages, but the design should avoid circular dependencies and ensure that subpackages do not depend on their superpackages.
  Transport Management: If you are working with transport requests, be aware that changes in package structure can affect transport routes and dependencies.
  Documentation: Always document any changes made to package structures or object dependencies to maintain clarity for future development and maintenance.
  
  Best Practices:
  
  Regularly review package dependencies during development to avoid such issues.
  Use naming conventions and documentation to clarify the purpose and relationships of packages and their objects.
  Consider using tools or transaction codes (like SE80 or SE11) to analyze dependencies and package structures effectively.
  
  By following these steps, you should be able to resolve the PAK163 error and maintain a well-structured package hierarchy in your SAP system.
