Trying to create a custom financial report to show YTD spend vs. FY budget vs. FY Forecast - how can I show two different Budget versions on the same financial report? I can't seem to select the budget version in the Edit Columns section, only on the report filters. What I want is to look side by side at Current Forecast vs. Budget.

My understanding is that displaying multiple budget versions isn't possible in NetSuite. You would need a third party reporting tool. I've heard solution7 is a good option

Also look at Vena https://www.venasolutions.com/solutions/financial-planning-analysis?

You can also try SuireAnalytics Workbooks where base record is Budget if your use case isn't that complicated.
