Smart SAP Assistant

• What is the cause and solution for SAP error message WSUBST002 - Select at least one row ?

  The SAP error message WSUBST002: "Select at least one row" typically occurs in scenarios where the user is expected to select one or more rows from a list or table before proceeding, but no row has been selected.
  
  Cause:
  
  The user interface (UI) or transaction expects the user to select at least one row (e.g., a line item, a record, or an entry) from a displayed list.
  The user tries to continue or execute an action without selecting any row.
  This validation is implemented to ensure that the subsequent processing has the necessary data to work on.
  
  
  Where it commonly occurs:
  
  In SAP Web Dynpro applications.
  In selection screens or list displays where multiple entries are shown.
  In transactions or custom developments where row selection is mandatory before proceeding.
  
  
  Solution:
  
  Select at least one row from the list or table before clicking the next button or executing the action.
  If the user is unsure which row to select, review the list and choose the relevant entry or entries.
  If this error occurs unexpectedly (e.g., the user believes a row is selected), check for UI issues such as:
  
  Incorrect or missing user input.
  UI controls not properly capturing the selection.
  Possible bugs in custom code or enhancements.
  
  
  
  
  Additional related information:
  
  This message is a standard validation message to prevent processing without required input.
  If you are a developer or consultant and encounter this message in a custom Web Dynpro or SAPUI5 app, ensure that the selection logic is correctly implemented and that the UI control binding is correct.
  In some cases, the message class is WSUBST and message number 002.
  You can check the message details in transaction SE91 by entering message class WSUBST and message number 002.
  If the issue persists despite selecting rows, debugging the application to verify the selection state might be necessary.
