Remember field status before importing new data
We import a rolling 4 week view of orders (from external) into a numbered list very week, this list is then used as a soruce for a model. In the module there is a booelan for 'approved' the user ticks orders that are aproved so they dont have to check again.
We clear the list each week and import fresh data. I want to keep the approved Boolean for any previous ticked orders. I have tried to export to another numbered list, but then can not get it back. I am sure this should be simple but am stuck. Any suggestions please?
