This window is available at Additional > Accrued Purchase Tax when the Payables Transaction Entry window is open in Microsoft Dynamics GP.
Permission to access this window is contained in the Purchase Entry Task.
The DZ Tax Detail Entry window is similar to the Payables Tax Detail Entry window and has the same functions. You can add, delete, or modify the tax detail records displayed in this window.
The Payables Tax Detail Entry window is used to record the use tax being charged by the vendor (billed). The DZ Tax Detail Entry window is used to record the use tax accrued on the transaction. The difference between the two is what is owed to the government (net).
