• What is the cause and solution for SAP error message WL381 - Operation '&&&' cannot be evaluated because object '&' has no value ?

  The SAP error message WL381 indicates that there is an issue with the evaluation of an operation in a workflow due to a missing value for a specific object. This typically occurs in the context of SAP Business Workflow, where certain conditions or operations depend on the values of workflow objects.
  Cause:
  The error message "WL381 Operation '&&&' cannot be evaluated because object '&' has no value" usually arises from one of the following reasons:
  
  
  Uninitialized Workflow Object: The workflow object that is being referenced in the operation has not been initialized or assigned a value. This can happen if the workflow is not properly set up or if there is a logic error in the workflow definition.
  
  
  Incorrect Workflow Logic: The workflow logic may be incorrectly defined, leading to a situation where an operation is trying to evaluate an object that is expected to have a value but does not.
  
  
  Data Not Passed: If the workflow is dependent on data being passed from a previous step or task, and that data is not available or not passed correctly, it can lead to this error.
  
  
  Condition Evaluation: If the operation is part of a condition that checks for the value of an object, and that object is empty or null, the evaluation cannot proceed.
  
  
  Solution:
  To resolve the WL381 error, you can take the following steps:
  
  
  Check Workflow Definition: Review the workflow definition to ensure that all objects are properly initialized and assigned values before they are used in operations. Make sure that the workflow logic is correctly defined.
  
  
  Debugging: Use the SAP Workflow log and debugging tools to trace the execution of the workflow. Identify where the object is expected to be assigned a value and check if that step is being executed correctly.
  
  
  Initialize Objects: Ensure that all necessary objects are initialized with default values if they are not set by previous steps. This can prevent the error from occurring during evaluation.
  
  
  Review Data Flow: Check the data flow between workflow steps. Ensure that any data required for the operation is being passed correctly from one step to another.
  
  
  Error Handling: Implement error handling in the workflow to manage cases where an object might not have a value. This can include setting default values or providing alternative logic.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance related to the workflow you are working on, as there may be known issues or best practices.
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the WL381 error.
  Workflow Monitoring: Use transaction codes like SWI1 (Workflow Overview) or SWI2_FREQ (Work Item Selection) to monitor workflow instances and identify issues.
  SAP Community: Engage with the SAP Community for insights and solutions from other users who may have encountered similar issues.
  
  By following these steps, you should be able to identify the root cause of the WL381 error and implement a solution to resolve it.
