• What is the cause and solution for SAP error message SWL_WP042 - Top label "&" contains invalid characters ?

  The SAP error message SWL_WP042, which states that "Top label '&' contains invalid characters," typically occurs in the context of SAP Workflow. This error indicates that there is an issue with the naming convention of a workflow or a related object, specifically that the top label (or name) contains characters that are not allowed.
  Cause:
  
  Invalid Characters: The top label of a workflow or task may contain special characters, spaces, or symbols that are not permitted by SAP naming conventions. For example, characters like &, #, %, etc., are often restricted.
  Incorrect Configuration: The workflow might have been incorrectly configured, leading to the use of invalid labels.
