Create a DS Microflow for the list which is displayed and remove the duplicates as shown below
Hope it helps!!!
If you want to achieve this you should use a data source microflow for the listview. In the datasource you retrieve all items of this entity, create a new list of this entity called entity_Show and loop over the items on the original list.
Here you use the list operation ‘find’. If you find an item with the same name in entity_show then do nothing and go to a continue event, if the item is not yet found add the iterator to entity_show, this is the list you will give back in the end event.
Then you can set a default button that when you click on an item, a microflow will retrieve all other items with the same name and show these on a page.
Hope this helps!
P.s. Looking at the issue you are facing, you might want to change your domain model. Set the SCName attribute on a seperate entity and associate this with the entity you are showing now. Now you can show the new entity in the listview and use another listview on the right, with the listen to widget datasource, which shows all the associated items.
