Recreate UNIQUE function

[saasyp]

Hi everyone, I'm trying to implement the following Excel SUMIF Formula:

 SUMIF('Tabella raggr'!B:B;T2;'Tabella raggr'!D:D) 

Basically I have to add up all the values in column D where the corresponding value in column B matches the value in T2.
In the screenshots below you can find the B and D columns of the 'Tabella raggr' table and the T2 which is the criteria of the SUMIF function and it's on another table called 'SAP'.

Hey @saasyp , 

I guess that you want to add this on your Airtable base right? To do that I would recommend to use rollups fields with the linked field.
