Does anyone use Zone billing (ZAB) and NS ARM module? We use both and I need to create a saved search report to pull in the ZAB revenue details from the related record of the invoice record. Please let me know if this is possible via a saved search or a suite analytics. Thank you.

Your best bet is to try running a search on the ZAB Revenue Transaction Link and joining each from there. Those get created after running the Update Revenue Details process. You should get a link for every line back to the Revenue Detail(s)
