Hi @HideyoshiAkaio ,
Thank you for posting query on Microsoft Q&A Platform.
Dataflows doesn't have ForEach kind of functionality but still you can write your output back to Pipeline activities using write output cache in Sink. Click here to know more about it.
How ever, you may also consider doing same using Lookup activity & Filter activity. Lookup activity to get all data from source in array format and then Filter activity to filter specific data items alone and then pass this to ForEach activity as per requirement.
Hope this helps. Do let us know if you any further queries.
