• What is the cause and solution for SAP error message WER_UI002 - Please select only one field ?

  SAP Error Message:
  
  WER_UI002 - Please select only one field
  
  Cause:
  This error occurs when a user selects more than one field in a context where the system expects only a single field selection. For example, in certain SAP UI screens or selection dialogs, the logic requires the user to pick exactly one field to proceed, but multiple fields have been selected instead.
  
  Solution:
  
  Select only one field: Review your selection and ensure that only one field is selected before proceeding.
  Check UI controls: If the UI allows multiple selections by mistake, verify if there is a configuration or UI control (like radio buttons or single-select dropdowns) that restricts selection to one field.
  User training: Inform users about the requirement to select only one field in that particular step or screen.
  Debugging (if applicable): If you are a developer or consultant and this error appears unexpectedly, check the code or configuration that triggers this message. Ensure that the selection logic enforces single selection and that the UI elements are correctly configured.
