Looping through a filter and save every iteration
Guru
Hello,
I already searched the forum but the given processes seem to be outdated and not compatible with the most recent version of RM.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:

Hi @MPB_,
"I would like to loop thorugh a filter in a way that for every attribute of the column "UPC" (=Universal Product Code) a new exampleset is stored."
Your request is not clear :
You mean every value of the column "UPC" ?
Moreover you XML process is broken, I can not import it in RapidMiner. Can you please export your process via File -> Export Process
and share the file here in the community ?
Can you also share your data ?
Regards,
Lionel

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,
