Explanation
Run taxes from all applicable tax regimes against a sample transaction to verify that your tax configuration and tax rules were created and applied according to yourrequirements. You can either create a sample transaction within Tax Simulator or copy an existing transaction. The simulated tax calculations do not affect live data.
Note:The Tax Simulator is a tool for simulating the tax determination process in your tax setup. The Tax Simulator lets you preview the workings of your tax configuration before you perform tax calculations on live transactions in a subledger application. TheTax Simulator also allows you to test new tax configuration in conjunction with existing tax configuration to preview the resulting tax calculation. The Tax Simulator is a useful tool to identify the root cause when tax calculation is not what is expectedon live data.
