• What is the cause and solution for SAP error message WOD1012 - Only select one line ?

  SAP Error Message:
  
  WOD1012 - Only select one line
  
  Cause:
  This error occurs when a user tries to perform an action that requires exactly one line (record) to be selected in a list or table, but either no line or multiple lines are selected. The system expects a single selection to proceed with the operation, such as editing, displaying details, or processing a specific entry.
  
  Solution:
  
  Select exactly one line: Before executing the action, ensure that you select only one line in the list or table.
  Deselect extra lines: If multiple lines are selected, deselect all except the one you want to work with.
  Check the UI controls: Sometimes, the selection might not be obvious (e.g., a checkbox or highlight). Make sure the selection is clear and only one line is active.
  Review the process: If the action logically requires multiple lines, verify if you are using the correct transaction or function. Some functions only support single-line processing.
  
  
  Related Information:
  
  This message is common in SAP modules where list processing is involved, such as Logistics, Finance, or Workflow.
  The message ID is usually WOD (Workflow Object Directory) or related to list processing.
  If you encounter this message in a custom program or report, check the selection logic in the code to ensure it enforces single-line selection where required.
  In some cases, the UI might allow multiple selections, but the backend logic only supports one. This discrepancy causes the error.
  Refer to SAP Notes or documentation related to the specific transaction or module if the problem persists.
  
  
  Summary:
  
  WOD1012 means you must select exactly one line to proceed. Select only one line and retry the operation.
