value change detection and Alert - Table without history

Hi guys, i need your help on this

I have a report and a want to set my alerts. on some cards i count errors, uncompleted actions, etc so the value depends on the category. I want to set an alarm for those values (i use power automate too) but i dont want to use a specific threshold. I want to create an alert when a value changes  (e.x. 5 errors - > 2 errors - after refresh) . My data is being retrieved from an sql db without history. I use a stored procedure and every 1 minute i delete the previous table and feed it with the new data. I use power automate to refresh the dataset every 1 minute on my powerbi report (personal gateway). So could you please help me how i could create an alert regarding the change value detection, or if is it possible to create a dynamic field  as threshold with the value of each category before the refresh and check if the dif between the 2 values, lastrefresh- previous =0?

Thank you in advance
