How To Fix WD378 - Outcome "&" has no ID. Please define an ID.

WD378 - Overview

• Message type: E = Error

• Message class: WD - Workflow definition

• Message number: 378

• Message text: Outcome "&" has no ID. Please define an ID.

What causes this issue?

The check for an activity returned an error because no ID was defined
for an active outcome.
There are two use cases for the ID of the outcome:
Use within an application callback.
The flexible workflow allows the application in callback methods to
respond to events. Within callback methods the program can access the
ID of the outcome. The following callback methods allow access to the
ID of the outcome:
IF_SWF_FLEX_IFS_RUN_APPL~RESULT_CALLBACK
With parameter IO_RESULT you obtain a result object, which returns the
result using method GET_RESULT. Component
WI_ID: ID of the workflow
WI_TYPE: Type of the workflow (F)
RESULT: <ZH>ID of the Outcome in the Scenario</>
NATURE: Property (positive, negative, ...)
ACTOR: Name of the agent
IF_SWF_FLEX_IFS_RUN_APPL_STEP~AFTER_COMPLETION_CALLBACK
With parameter IO_CURRENT_ACTIVITY and method
IO_CURRENT_ACTIVITY->GET_EXECUTION_RESULTS a list of the last results
can be retrieved. The component RESULT contains the ID of the outcome.
The ID of the outcome is assigned in the modelling scenario by the
application developer and should be extracted from the technical event.
Exposure in the CDS I_WorkflowStepResult
The CDS view I_WorkflowStepResult exposes the potential results
(outcomes) of a step. Outcomes with no ID are not exposed. This means
that for a completed task instance, no further information about the
outcome (result) of the instance can be displayed.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

On the table ?Outcomes?, enter an ID and a property (positive, negative,
neutral) for each active outcome. The IDs of an activity must be unique.
Please note that when an ID is changed, it can lead to unwanted side
effects, for example, the semantics of a result is changed.

• What is the cause and solution for SAP error message WD378 - Outcome "&" has no ID. Please define an ID. ?

  SAP Error Message:
  WD378 Outcome "&" has no ID. Please define an ID.
  
  
  Cause:
  This error occurs in Web Dynpro applications when an outcome (navigation action) is defined without an associated ID. In Web Dynpro, navigation between views or components is controlled by outcomes, and each outcome must have a unique ID. If an outcome is referenced or used without an ID, the framework cannot identify it properly, leading to this error.
  Common scenarios causing this error:  
  
  An outcome is declared in the Web Dynpro component or view but the ID property is missing or empty.  
  The navigation action is triggered programmatically or via UI elements, but the outcome ID is not set or incorrectly referenced.  
  The outcome is defined with a placeholder or special character (like "&") instead of a valid ID.
  
  
  
  Solution:
  
  
  Check Outcome Definitions:  
  
  Open the Web Dynpro component or view in the Web Dynpro Explorer.  
  Navigate to
