• What is the cause and solution for SAP error message PAK154 - For package &1 only use accesses to other structure packages are possible ?

  The SAP error message PAK154 indicates that you are trying to use a package that is not allowed for certain types of accesses. Specifically, it states that for the specified package (&1), only accesses to other structure packages are permitted. This typically occurs in the context of package dependencies and access control in the SAP development environment.
  Cause:
  
  Package Type Restrictions: The package you are trying to use may be defined as a "structure package," which means it is intended to contain only certain types of objects and restricts access to other packages.
  Access Control: The package may have specific access control settings that prevent it from being used in certain contexts, such as in the implementation of business logic or in other packages that are not structure packages.
  Dependency Issues: There may be dependencies on other packages that are not compatible with the current package's settings.
  
  Solution:
  
  Check Package Attributes: Go to the package in question and check its attributes. Ensure that it is set up correctly for the intended use. You can do this by navigating to the package in the SAP GUI and reviewing its properties.
  Use Structure Packages: If you need to access objects from the package, ensure that you are only accessing them from other structure packages or adjust your design to comply with the restrictions.
  Adjust Access Settings: If you have the necessary authorizations, you may consider changing the access settings of the package to allow broader access. However, this should be done with caution and in accordance with your organization's development guidelines.
  Consult Documentation: Review SAP documentation or consult with your SAP Basis or development team to understand the implications of changing package settings and to ensure compliance with best practices.
