  SAP Error Message:
  
  WTYC1018 - Function code for action &1 has not been maintained
  
  Cause:
  This error occurs when a function code assigned to a particular action in a workflow or a related SAP component has not been properly maintained or configured in the system. Essentially, the system expects a function code to be defined for a specific action, but it cannot find it in the customizing or configuration tables.
  Common scenarios where this happens include:
  
  Missing or incomplete configuration in workflow customizing.
  Missing function code assignment in transaction codes or user actions.
  Custom developments or enhancements where function codes are referenced but not maintained.
  Missing entries in tables like TBTCO, TBTCP, or workflow-related customizing tables.
  
  
  Solution:
  
  
  Check the Action and Function Code Configuration:
  
  Identify the action for which the function code is missing.
  Go to the relevant customizing transaction (often in Workflow or the application area related to the error).
  Maintain or assign the correct function code for the action.
  
  
  
  Workflow Customizing:
  
  Use transaction SWDD (Workflow Builder) or SWU3 (Workflow Customizing) to check the workflow steps and actions.
  Verify that all actions have function codes assigned.
  If missing, maintain the function code in the workflow step or action.
  
  
  
  Check Table Entries:
  
  Check tables like TBTCP (Workflow Container Elements), TBTCO (Workflow Header), or other relevant tables for missing function code entries.
  Use SE16/SE16N to verify if the function code exists.
  
  
  
  Transport and Development Checks:
  
  If this error occurs after a transport or development change, verify that all necessary customizing and function codes were transported correctly.
  Check if any custom function codes need to be created or maintained.
