  SAP Error Message: WF_CONT065 - Specify a class name
  
  Cause:
  The error WF_CONT065 occurs in SAP Workflow when a class name is expected but has not been specified. This typically happens in the context of workflow container elements or workflow methods where the system requires a reference to a class (usually an ABAP class) but the field is left empty or incorrectly maintained.
  Common scenarios include:
  
  Defining a container element in a workflow step or task where the data type is set to "Object" but the class name is missing.
  When creating or editing a workflow container element or method parameter, the class name is mandatory if the data type is an object reference.
  In workflow tasks or methods that expect an object reference, the class name must be specified to identify the type of object.
  
  
  Solution:
  To resolve the error WF_CONT065, you need to specify the correct class name in the relevant workflow container element or method parameter.
  Steps to fix:
  
  
  Identify where the error occurs:
  
  Check the workflow step, task, or method where the container element is defined.
  Look for container elements or parameters that have the data type set as "Object Reference".
  
  
  
  Specify the class name:
  
  Go to the container element or method parameter definition.
  If the data type is "Object Reference", enter the appropriate ABAP class name in the "Class" field.
  The class name should be a valid ABAP class that exists in the system and is relevant to the workflow process.
  
  
  
  Save and activate:
  
  After specifying the class name, save and activate the workflow or task.
  Test the workflow again to ensure the error no longer appears.
  
  
  
  
  Additional Information:
  
  
  Where to check container elements:
  
  Transaction SWDD (Workflow Builder) ? Open the workflow ? Go to container tab ? Check container elements.
  
  
  Class names in workflows:
  
  Workflow container elements can be of elementary types (like CHAR, NUMC) or object references. For object references, the class name is mandatory.
  
  
  Related SAP Notes:
  
  Sometimes, this error can be related to missing or incorrect configuration in custom workflows. Checking SAP Notes or OSS messages related to workflow container elements might help if the problem persists.
  
  
  Debugging tip:
  
  If unsure which container element is causing the issue, activate the workflow with trace (SWI1 or SWI2_DIAG) and analyze the logs to pinpoint the missing class name.
