• What is the cause and solution for SAP error message WXP160 - Select one line in both lists ?

  SAP Error Message:
  
  WXP160 - Select one line in both lists
  
  Cause:
  This message typically appears in SAP Web Dynpro applications or SAP GUI screens where the user is required to select exactly one entry (one line) from two different lists or tables before proceeding. The error occurs because the user has either:
  
  Not selected any line in one or both lists, or  
  Selected multiple lines in one or both lists, whereas the application expects exactly one line selected in each list.
  
  
  Solution:
  
  Ensure that exactly one line is selected in each of the two lists before you proceed.  
  If no line is selected, select one line in each list.  
  If multiple lines are selected, deselect all but one line in each list.  
  After making the correct selections, try to continue or execute the action again.
  
  
  Related Information:
  
  This message is often encountered in scenarios involving dual list selection, such as assigning or mapping entries from one list to another.  
  The message is a warning or error to enforce correct user input and prevent ambiguous or incomplete processing.  
  If you are a developer or consultant, ensure that the UI logic enforces single selection mode on both lists or provides clear instructions to the user.  
  Check the underlying code or configuration for the selection controls (e.g., radio buttons or single-selection tables) to ensure they are set to allow only one selection.  
  In Web Dynpro, this might involve checking the properties of the UI elements or the event handlers that validate the selection.
