• What is the cause and solution for SAP error message SWDP_WB_TOOL573 - &1: onChange and onEnter must not be used at the same time ?

  The SAP error message SWDP_WB_TOOL573 indicates that there is a conflict in the usage of the onChange and onEnter event handlers in your Web Dynpro application. This error typically arises when both event handlers are assigned to the same UI element, which is not allowed.
  
  Cause:
  The error occurs because:
  
  The onChange event is triggered when the value of an input field changes and the user leaves the field (focus is lost).
  The onEnter event is triggered when the user presses the Enter key while the input field is focused.
  
  Using both event handlers simultaneously on the same UI element can lead to ambiguity in how the application should respond to user input, hence the error message.
  
  Solution:
  To resolve this error, you need to ensure that you are using either onChange or onEnter, but not both, for the same UI element. Here are the steps to fix the issue:
