• What is the cause and solution for SAP error message EPIC_LOGON017 - Use 'Implementing Class' in customer namespace ?

  The SAP error message EPIC_LOGON017 indicates that there is an issue related to the implementation of a class in the customer namespace. This error typically arises in the context of SAP's Enterprise Portal or when dealing with custom developments in the SAP environment.
  Cause:
  The error message suggests that the system is expecting an implementation of a class that should be defined in the customer namespace (usually starting with a specific prefix like Z or Y). This can occur due to:
  
  Missing Implementation: The required class implementation is not found in the customer namespace.
  Incorrect Configuration: The system might be configured to look for a class that is not properly defined or activated.
  Transport Issues: If the class was recently transported from another system, it may not have been transported correctly or may be missing dependencies.
  
  Solution:
  To resolve the EPIC_LOGON017 error, you can follow these steps:
  
  
  Check Class Implementation:
  
  Go to the ABAP Workbench (transaction SE80 or SE24) and check if the class that is expected is implemented in the customer namespace.
  If it is missing, you may need to create it or transport it from another system.
  
  
  
  Review Configuration:
  
  Ensure that the configuration settings that reference the class are correct. This may involve checking the portal configuration or any related settings in the SAP system.
  
  
  
  Transport Management:
  
  If the class was supposed to be transported, check the transport logs to ensure that it was successfully imported into the target system.
  If there are issues with the transport, you may need to re-transport the class or its dependencies.
  
  
  
  Check for Dependencies:
  
  Ensure that all dependencies of the class are also present in the customer namespace. Sometimes, a class may depend on other classes or interfaces that also need to be implemented.
