Use this form to define and review your Oracle Purchasing System Options, which are the default and control values for corresponding fields throughout Oracle Purchasing. You can often override these default values from the particular forms. You normally first use this form as part of your implementation of Oracle Purchasing. Setting up specific values in this form saves you time when you create your requisitions, purchase orders and agreements, receipts, quotations, and RFQs.
Oracle Purchasing lets you define specific categories of system options when you enter one of the following values in the Additional Purchasing Options field.
1) Default Options - Use the Default Options region to define the defaults you can later use to speed up data entry and enforce system wide requirements in many Oracle Purchasing forms. Oracle Purchasing displays the Default Options region when you initially enter the form.
2) Accrual Options - Use the Accrual Options region to define accrual options, such as whether you accrue expense items at period end or upon receipt.
3) Control Options - Use the Control Options region to define control options, such as the receipt close point and minimum release amount.
4) Internal Requisition Options - Use the Internal Requisition Options region to define internal requisition options, such as the order type and terms. You can navigate to this region only when Oracle Order Entry and Oracle Inventory are installed.
5) Numbering Options - Use the Numbering Options region to define the numbering method, numbering type, and next number for each of your documents.
6) Approval Options - Use the Approval Options region to define system wide approval controls, such as whether you want to enforce price tolerances and vendor holds.
7) Tax Defaults Options - Define the sources from which purchasing documents default tax information. Check one or more of the tax defaults sources from which your purchasing documents default tax codes. In the Hierarchy column, enter a ranking number (starting with 1) for each of the tax defaults sources you checked (even if you checked only one). For example, you may check Item, Supplier Site, and Supplier and rank them 3, 2, and 1 respectively. This means that when your purchasing documents default tax information, they look first for tax information from the supplier; if that tax information is not found, they look next for tax information from the supplier site; if that's not found, they look for tax information corresponding to the item.
