is anybody aware of how to create (SuiteScript, Suitelet) VAT report functionality for specific country like we can find in International tax report bundle? I mean how to create the form with all the boxes for data, how to populate the data (a lot of saved searches?) , what tool to use to get the report when user wants to drill down directly from a VAT form? I know its very wide question, so I wondering if anybody has developed smth similar?
