  • INCLUDES(Selected rows > column name>, defined value)—The action button is disabled or hidden if the defined value is included in the array.
  • SAME(Selected rows > column name)—The action button is disabled or hidden if the column values of the selected rows are the same in the array.
  • SIZE(Selected rows / Selected rows > column name)—The function returns the size or length of the selected rows. Use this function in conjunction with the INCLUDES()or SAME() functions. 

The following image shows an example of how you can disable an action button by creating an expression using the SAME() function:
