Hi @mustufam5967803,
I'm not sure what your existing workflow logic looks like, but could use a Query or Split activity to narrow down the tracking log records to just Email Clicks on those two CTAs before you get to the Dedup activity? For example:
[delivery/@name] = {delivery name}
AND
[url/@type] = Email click
AND
[url/@label] is included in CTA1, CTA2
Then you can use the Dedup as already described to calculate which happened first (in the event someone clicks on both).
Thanks,
Josh
