Use
It may be that no purchase requisition was created in the system for a certain requirement and the procurement process is to begin directly with a purchase order. This could be the case, for example, if the requirement was notified to Purchasing by ‘phone and the buyer wishes to create a PO immediately, even though he does not yet know which vendor is to receive it.
You have the option of using the source determination facility for such cases too.
As in requisition processing, the system suggests possible sources of supply for the material on the basis of existing quota arrangements, source list records, outline agreements, and/or info records.
Prerequisites
Before using this procedure, you should know how to create requisitions and purchase orders manually.
Activities
To create a PO with source determination, proceed as follows:
The initial screen appears.
Select the Source determination field if the source is to be determined automatically and assigned to a PO item after entry of the latter.
Press ENTER to display the item overview screen.
You can also adopt items from an existing requisition by choosing Purchase order ® Copy requisition.
The system lists the possible sources for the material. If only one vendor exists for an item, the vendor is assigned to the item automatically. You can determine which vendor has been assigned to an item by displaying the item details.
Position the cursor on the desired source in the dialog box and choose Price simulation. A second box appears, in which you enter the simulation data. Press ENTER to display the conditions for the source.
If no suitable source currently exists for an item, you can save the latter as a requisition item so that already entered data is not lost.
Select the items to be saved in this way, then choose Purchase order
®
Save as requisition.
You can also save items that cannot be converted into PO items (because they are subject to a release procedure, for instance) as purchase requisition items.
If you have defined different document types for requisitions than those you defined for purchase orders, a dialog box appears. Use this box to change the document type.
The system consolidates the items for the selected vendor and generates a purchase order. The system then issues an appropriate message.
