• What is the cause and solution for SAP error message PAK079 - Package interface &1 exists only in the buffer ?

  The SAP error message PAK079 indicates that a package interface exists only in the buffer and is not available in the database. This typically occurs in the context of SAP's package management and can be related to issues with the transport of package interfaces or inconsistencies in the system.
  Cause:
  
  Buffer Inconsistency: The package interface may have been created or modified in the system but has not been properly transported or activated in the database.
  Transport Issues: If the package interface was recently transported from another system, it may not have been fully imported or activated.
  Development Environment: The error may occur in a development environment where changes have been made but not yet released to the quality or production environments.
  
  Solution:
  
  Check Buffer Status: Use transaction code SE80 or SE11 to check the status of the package interface. Ensure that it is correctly defined and activated.
  Activate the Interface: If the interface exists in the buffer but not in the database, try to activate it. You can do this by navigating to the relevant package in SE80 and activating the interface.
  Transport Request: If the interface was supposed to be transported, check the transport request to ensure it was released and imported correctly. You can use transaction code STMS to manage transport requests.
  Clear Buffer: In some cases, clearing the buffer may help. You can do this using transaction code /$SYNC or by using the program RS_ABAP_BUFFER_CLEAR.
  Check for Errors: Look for any errors in the transport logs or activation logs that might indicate why the interface is not available in the database.
  Consult Documentation: Refer to SAP documentation or notes related to package interfaces for any specific instructions or known issues.
