  The SAP error message WER_UI003: Invalid input, see message log for details typically occurs in the context of SAP Workflow or Business Workplace (SBWP) when a user inputs data that does not meet the expected format or validation rules.

  UI or screen issues: Sometimes, the UI component or screen might not properly handle the input or display the correct validation messages.
  
  
  Solution
  
  
  Check the message log:
  
  The error message suggests looking at the message log for details. In SAP Workflow or Business Workplace, you can check the message log to find the exact validation error.
  In transaction SBWP (Business Workplace), open the workflow or task and check the message log or error log.
  In workflow tools (e.g., SWI1, SWI2_FREQ), check the workflow container and logs.
  
  
  
  Validate input data:
  
  Ensure all mandatory fields are filled.
  Verify that the data format matches the expected format (e.g., date, number, text length).
  Correct any invalid or inconsistent data.
  
  
  
  Review custom validations:
  
  If custom validations are implemented (via user exits, BADIs, or workflow container checks), review the code to understand what input is expected.
  Debug the workflow or UI component to trace where the validation fails.
  
  
  
  Check UI components:
  
  If the error occurs in a Web Dynpro or Fiori UI, check the input field validations and data binding.
  Ensure that the UI is correctly passing data to the backend.
  
  
  
  Reprocess or restart the workflow:
  
  After correcting the input, reprocess the workflow task or restart the workflow instance if necessary.
