The setup is as such. One main list, Then a second list with a look up column for the asset items that include, Asset tag, Serial number, model number and such. Then on infopath 2013, create a form on the main list. Then add the lookup column as a multi-selection type to only show the asset tag, Make sure to have two data sources for the lookup. One for the Asset Tags and one for the Items. So Data source with ID and Tag and the other named. Asset Items that will import serial numbers and models and such. I'm able to display one serial number at time, Based on the asset tag selected, But I need to be able to have to display more than one serial number if I choose more than one asset tag.
