• What is the cause and solution for SAP error message WER_UI131 - Please select only element set at a time from the table ?

  SAP Error Message:
  
  WER_UI131 – "Please select only element set at a time from the table"
  
  Cause:
  This error occurs when a user tries to select multiple element sets simultaneously from a table or list where only one element set selection is allowed at a time. In SAP, certain UI components or selection screens restrict the user to select only a single element set to avoid ambiguity or processing errors.
  For example, in scenarios involving Workflows, Business Rules, or certain configuration tables, the system expects the user to pick one element set to proceed. Selecting more than one violates this rule, triggering the error.
  
  Solution:
  
  Select only one element set at a time: Review your selection in the table and ensure that only a single element set is selected before proceeding.
  Clear multiple selections: If multiple rows or checkboxes are selected, deselect all except one.
  Check UI instructions: Sometimes the UI or help text indicates that only one selection is allowed; follow these instructions carefully.
  If using custom code or enhancements: Verify that the code enforces single selection and does not allow multiple selections programmatically.
  
  
  Related Information:
