Comparing values between different tables
Hello, I have a table "LIST" composed by three columns: ID, COD, VALUE. I have another table "CONTAINER" composed by two columns : COD , SUM_OF_VALUE I would like to save in the SUM_OF_VALUE column...
Ok. If you're using Power BI Desktop you just need to apply both your tables to the model, relate LIST to CONTAINER on CONTAINER[COD] 1 = * LIST[COD] (assuming your CONTAINER table contains a UNIQUE list of customers), then drag CONTAINER[COD] and LIST[VALUE] columns into a visual. PBI will automatically aggregate the result giving you what it sounds like you're after.
If this is to be done in Excel, then probably easiest to just do a merge in PQ instead of a relationship as described above in the model.

Use merge query in Power Query, or load the data into the model and use DAX to calculate (aggregate and then determine whether it is greater than 0).
