Correcting Transaction Tax Amounts
Depending on how you set up GTM, you can selectively override system-calculated tax amounts. The default behavior is determined first by Update Tax Allowed in Global Tax Management Control (29.24), then by the same field in individual tax rate records (29.4.1).
In transactions, View/Edit Tax Detail always lets you review how the system calculated taxes. If Update Tax Allowed is Yes, you can also change the taxable base, tax, and recoverable tax amounts.
Use this feature to match amounts on manually issued documents. Typically, you edit tax amounts only when transaction tax amounts must exactly match an external document. You can also edit taxes when entering transactions for which you have not set up standard rates. However, the system does not maintain an audit trail of changes, so accounting regulations may prevent you from using this capability.
If you do edit tax amounts, one of the following messages displays when you exit transactions:
Recalculate Tax
Enter Yes to recalculate tax and taxable base amounts based on the current data you entered in the transaction. Do this if you ship or receive a different quantity than originally entered.
Copy Edited Tax Values
Enter Yes to copy previously edited tax amounts to this transaction or No to recalculate taxes based on current transaction information.
For example, when you enter a purchase order, you can manually edit the system-calculated tax amounts. When you process the receipt, copy the edited tax values from the order or recalculate taxes based on the current information. If you did not manually edit the taxes in the order, taxes are automatically recalculated at receipt.
If you enter Yes, the system copies tax amounts from the earlier transaction to the one you are currently working on. If you enter No, the system recalculates taxes. Taxes are copied exactly. The system does not adjust for quantity or price differences between the two transactions.
