Pega Platform - importing data
I am importing data into the pega platform via a CSV excel spreadsheet. This data includes multiple codes in column A, with different usernames in column B. This data includes duplicate codes with the names also duplicate at times, in column B, which is what I need. I then have a form where I select the code from a picklist, however the platform seems to be deleting all duplicates, so that when I type the code I require, it only shows me one potential username corresponding to that code, as opposed to giving me the option of multiple names.
Is there any way I can configure the form to allow me to import the data and then select which user from that code I would like to select?
