Looping through a filter and save every iteration

I already searched the forum but the given processes seem to be outdated and not compatible with the most recent version of RM.

I have a big dataset with sales-data of many products, many supermarkets, many weeks....

I would like to loop thorugh a filter in a way that for every value of the column "UPC" (=Universal Product Code) a new exampleset is stored.
Is that possible?

My process looks like this:

<?xml version="1.0" encoding="UTF-8"?><process version="9.5.000">

    Hi @MPB_

    Just to add on this. If Lionel is right and you want to loop over every value of the column "UPC", you can use the operator Group Into Collection from the Operator Toolbox Extension (install it over the marketplace). This creates a collection with individual ExampleSets for each value of the column "UPC". You can use Loop Collection to iterator over the collection and store each ExampleSet individually.

    Best regards

    Thank you again and have a very nice week,
