• What is the cause and solution for SAP error message WL384 - Result of operation & & & is multiline ?

  The SAP error message WL384 indicates that the result of an operation is multiline, which typically occurs in the context of SAP's workflow or business process management. This error can arise when a workflow step or operation is expected to return a single line of output, but instead, it returns multiple lines, leading to confusion or processing issues.
  Cause:
  
  Multiline Output: The operation or function module being called is returning a result that contains multiple lines of text or data, which is not handled properly by the subsequent processing logic.
  Incorrect Configuration: The workflow or process may be incorrectly configured to expect a single line of output when it should be able to handle multiline results.
  Data Formatting Issues: The data being processed may not be formatted correctly, leading to unexpected multiline results.
  
  Solution:
  
  Check the Function Module/Method: Review the function module or method that is generating the output. Ensure that it is designed to return a single line if that is the expected behavior.
  Modify Workflow Logic: If the workflow is designed to handle only single-line outputs, consider modifying it to accommodate multiline results. This may involve changing how the output is processed or displayed.
  Data Handling: If the data being processed is expected to be multiline, ensure that the subsequent steps in the workflow can handle multiline data appropriately. This may involve using string manipulation functions to parse or format the output correctly.
  Error Handling: Implement error handling to manage cases where multiline output is encountered unexpectedly. This can help prevent the workflow from failing and provide more informative error messages.
