  The SAP error message WZRE_PRX217: Customizing reader cannot be instantiated typically occurs in the context of SAP Workflow or Business Workflow when the system tries to instantiate or access a customizing reader class but fails.
  
  Cause
  
  Missing or incorrect class implementation: The error indicates that the system is unable to instantiate the class responsible for reading customizing data. This can happen if the class is not available, not active, or incorrectly specified in the workflow customizing.
  Incorrect configuration in workflow customizing: The workflow might be configured to use a specific customizing reader class that does not exist or is not properly maintained.
  Transport or system inconsistencies: Sometimes, after transports or system upgrades, the class or related objects might be missing or inconsistent.
  Authorization issues: The user or system might lack the necessary authorizations to instantiate or execute the class.
  
  
  Solution
  
  
  Check the class existence and activation:
  
  Use transaction SE24 (Class Builder) to check if the class mentioned in the error or workflow customizing exists and is active.
  If the class is inactive, activate it.
  
  
  
  Verify workflow customizing:
  
  Go to transaction SWU3 (Automatic Workflow Customizing) and check if the customizing reader class is correctly maintained.
  Alternatively, check the workflow container or customizing tables where the class is specified.
  
  
  
  Check for transport or system inconsistencies:
  
  If the error appeared after a transport or system upgrade, verify that all relevant objects were transported correctly.
  Reimport or reapply transports if necessary.
  
  
  
  Check authorizations:
