Here are couple of ways you could achieve this:
Option 1: Copy the values over to persistent entity.
- Create a list of entity Test which needs to be committed
- Inside the loop create the object of entity Test and copy over the values from Iterator.
- Add the created object to the list
- Commit the list outside the iterator.
Note → You could also think of using the import mapping to directly store your data.
Use the same microflow to just return a type of list JsonObject.
Use this microflow as datasource for your list view
Although this option will work, based on the amount of data it might consume too much memory.
But the above two options would at least help in displaying the info you want and then you can think of how to design the system in terms of consuming the data.
Hope this helps!
