You can use the following data flow expression in the derived column:

iif( contains(split(Type, ' '), #item == 'Annual'), 'Annual', 
  iif( contains(split(Type, ' '), #item == 'Monthly'), 'Monthly',
  'None'))

Explanation:

  • split() functions convert each row in Type column into array. (i.e. the "Founding Annual Member" will be converted to ["Founding Annual Member"] )
  • contains() functions return true if the column contains the word "Annual" (first contains function), or "Monthly" (second contains function)
  • iif() functions evaluate the result of the contains() functions by returning the word "Annual" (iif in the first row), or "Monthly" (iif in the second row). If no matches found then the second iif() function returns the word "None". (last row)
