This window is used to record historically the deduction limits specified to apply deduction in purchase and sales transactions. It is located under Administration module > Definitions menu.
Provided that the relevant materials selected for the lines in Orders, Dispatches/Receipts and Invoices are applied deduction, and VAT included total of these lines is less than the value given in this table line for the relevant date range, deduction is not applied on the relevant slips. If the VAT included total is greater, then deduction is applied. Transaction amount must exceed 770,00 TRY including the calculated VAT. Transactions which do not exceed 770,00 TRY are not subject to deduction. This amount is stated by the government, and it may change periodically. With the intent of tracking the retrospective transactions, all deduction limits can be kept in this table. If there is no limit specified for the relevant transaction date entry, this indicates that a limit will not be applied.

New periods and deduction limit definitions can be made by using the "New" button located at the left bottom (F9) of this window.
