hello! we're integrating our data into NetSuite, but we have some use-cases which i'd appreciate some feedback if you've tackled such issues in the past: 1. we wanna start using the approval flow; what would be the best way to preview the impact of approving journals? we have a big volume of data; i created a saved search that mimic a general ledger, but i was wondering if there's a better way 2. due to our big data volume, we expect that we'll need to reverse some journals. we're using a custom field to mark those that will be reversed and created a saved search to show the impact; is there a better way to do this? 3. what would be the best way to update a big volume of journals? atm, we're thinking of creating a restlet that, when triggered, will start a map/reduce script that will use a pre-uploaded csv file thanks in advance!
