Hello everyone,

I' m new in Power Automate and Apps I just have started learning and I don't know how to fix this problem. What i want to do is to one combination of values can be add one time in sharepoint list.

For example:

I have three columns with this added items

Culumn1 | Column2 | column3





and what i want to do: if I want to add new item who look the same as the first one  AAA | BBB | CCC

the system don"t let me to do this. Is there any solution that use Power Automate or Power Apps or anything to do this :)? Please if yes sent screenshot for me to better understanding the solution.

Thank you in advance! :)
