• What is the cause and solution for SAP error message SWF_BND_001230 - Error when executing operation '&1': Operand '&2' not numerical ?

  The SAP error message SWF_BND_001230 indicates that there is an issue with a specific operation in a workflow or business process where an operand is expected to be numerical, but it is not. This error typically arises in the context of workflows, particularly when using the Business Workflow (SWF) functionality in SAP.
  Cause:
  The error occurs when:
  
  An operation is trying to perform a calculation or comparison using an operand that is not of a numerical type (e.g., a string or a null value).
  The workflow definition or the data being processed contains incorrect or unexpected values.
  There may be a mismatch in data types between what is expected and what is provided.
  
  Solution:
  To resolve the SWF_BND_001230 error, you can follow these steps:
  
  
  Check Workflow Definition:
  
  Review the workflow definition to ensure that all operands used in calculations or comparisons are correctly defined as numerical types.
  Look for any variables or parameters that are expected to be numerical but may have been defined incorrectly.
  
  
  
  Validate Input Data:
  
  Ensure that the data being passed to the workflow is valid and conforms to the expected data types.
  If the data is coming from user input or external systems, validate that it is being formatted correctly.
  
  
  
  Debugging:
  
  Use the workflow log or debugging tools in SAP to trace the execution of the workflow and identify where the error occurs.
  Check the values of the operands at runtime to see what is being passed and why it is not numerical.
  
  
  
  Error Handling:
  
  Implement error handling in the workflow to manage cases where non-numerical values might be encountered.
  You can add conditions to check the data type before performing operations.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific details about the operations being performed and the expected data types.
  
  
  
  Testing:
  
  After making changes, thoroughly test the workflow to ensure that the error is resolved and that it behaves as expected with various input scenarios.
