• What is the cause and solution for SAP error message WER081 - Application &1 does not have at least one structure. ?

  SAP Error Message:
  
  WER081 Application &1 does not have at least one structure.
  
  Cause:
  This error occurs when an application in the SAP Workflow system is expected to have at least one structure defined, but none is found. In SAP Workflow, an Application is a container for workflow-related objects such as methods, events, and structures. Structures are used to define the data types that the workflow will use to pass information.
  If the application does not have any structure assigned or created, the system raises this error because it cannot proceed without the necessary data definitions.
  
  When does it occur?
  
  When you try to create or activate a workflow that references an application without any structures.
  When you try to generate or use an application in the workflow builder or SWDD transaction, and the application is incomplete.
  During workflow import/export or transport if the application is incomplete.
  
  
  Solution:
  
  
  Check the Application in SWO1:
  
  Go to transaction SWO1 (Business Object Builder).
  Enter the application name mentioned in the error message.
  Check if the application has at least one structure defined under the "Structures" tab.
  
  
  
  Create a Structure if Missing:
  
  If no structure exists, create a new structure.
  Define the structure fields as required by your workflow.
  Save and activate the structure.
  
  
  
  Assign the Structure to the Application:
  
  Ensure the structure is assigned to the application.
  Activate the application after adding the structure.
  
  
  
  Check Workflow Builder (SWDD):
  
  After fixing the application, go back to the workflow builder.
  Re-import or refresh the application.
  Activate the workflow.
  
  
  
  Transport and System Consistency:
  
  If this error occurs after a transport, verify that the application and its structures were correctly transported.
  Re-import or fix the transport if necessary.
  
  
  
  
  Additional Information:
  
  Applications in SAP Workflow are defined in the Business Object Builder (SWO1).
  Structures define the data types used in workflow container elements.
  Without at least one structure, the workflow cannot pass data, hence the error.
  This error is common when custom applications are created but not fully defined.
  Always ensure that the application is complete with methods, events, and at least one structure before using it in workflows.
