    That's what i like about this application : options to discover thanks for the tip @Manuel

    another option would be splitting the column on '-'and truncating the outcome to the last occurance of that '-'. or the last two if '-'-containing countries is a concern.

    cheers!

    Hi,

    In a Prepare recipe, add a "Extract with Regular Expression" processor and then use the Smart Pattern Builder.

    I hope this helps.

    Hi Manuel, thanks for the tip. But i am not able to find the Smart Pattern Builder. Maybe mine is a lower version. However, really appreciate your kind advise as i now know the existence of this builder. Thank you and have a great weekend!
