Importing duplicate rows into a numbered list
One of the reasons for choosing a numbered list is that it supports duplicate combinations of properties. Does anyone know how you can import into a numbered list from a CSV containing duplicate rows? It is not acceptable to have to add anything to the CSV prior to import. For example the CSV has 3 columns headed List1, List2, Num1, with two data rows List1_1, List2_2, 1 and List1_1, List2_2, 1. The numbered list has Properties List1, List2 and Num1. If I were to Insert 2 entries into this list and then manually set the properties for each entry I could achieve the desired outcome, so why can't I do the same with an Import?
LIst imports are designed to support both creating and updating data - very often it's a mixture of both, sometimes known as 'upserting'. Some rows might fail, but if you correct the source data and re-import then only the previously-failed rows will be added to the list. Yes, you can denormalise the data manually (and use different composite keys for different imports), but most administrators spend a lot of effort trying to keep their master data manageable - and that usually means normal in the relational sense. If two items in a list are the same, there's rarely much value in them being distinct items, and quite a few disadvantages - you can't individually identify them for update without extracting the internal #numbers and pinning them back to the source somehow, for example.1
Instead of using Name or Code to import, you can try importing through "Combination of Properties". That should help in the given secnario.0
