Source Determination in Interactive Planning 

Use

If you create a procurement proposal in interactive planning in Production Planning and Detailed Scheduling (PP/DS) or Supply Network Planning, and there are several valid alternative sources of supply, you select the source of supply manually.

Features

When you create the procurement proposal, you branch to the dialog box Supply Source Determination. The dialog box contains various tab pages that are described in the following sections.

Sources tab page

This tab page shows the ranking list with the alternative, valid sources of supply for the location product that the system has prioritized on the basis of the quota arrangement, the procurement priority, the procurement costs, and the procurement type. The best source of supply according to these criteria is highlighted in green. In addition, you find detailed information for each source of supply – for example, if a source is quota-allocated. You can find out from the following dates if it is at all possible to stage a product with a source of supply for the desired availability date/time:

·        Latest delivery date/time

This date/time shows when, at latest, production or a supplier has to deliver the product to the warehouse in order that the desired availability date/time for the product can be adhered to. The system calculates this date/time by subtracting the goods receipt processing time from the desired availability date/time. If this date is in the past, the desired availability date cannot be adhered to.

·        Anticipated availability date/time

This date/time, which is only relevant to externally-procured products, shows the earliest time the product can be available. The system calculates this date/time by adding the planned delivery time and the goods receipt processing time to the current date/time. If the anticipated availability date/time is after the desired availability date/time, the source of supply can only stage the product with a delay.

The system flags sources of supply for which timely staging of the product is not possible with a yellow triangle .

The system calculates the dates while taking the relevant calendars into consideration, but without taking account of existing resource loads (infinite scheduling). In external procurement, the system uses the goods receipt processing time from the source of supply, while in in-house production it uses the goods receipt processing time from the location product master. For more information on scheduling, see Scheduling in the Case of External Procurement Orders.

Log tab page

This tab page contains the source determination log with all the sources of supply that the system has analyzed during source determination. On this tab page, you can also find sources of supply that may not be used. These include, for example, invalid sources of supply or transportation lanes that you have locked so that they cannot be used.

Quota Arrangements tab page

The system only shows this tab page if you have maintained quota arrangements. You can find information specific to quota arrangements here.

Activities

·        Display costs

On the Sources tab page, select the source of supply and choose  Costs. In the case of an external procurement relationship, the scale that is relevant to the desired procurement quantity is highlighted in green.

·        Select the source of supply

On the Sources tab page, select one or more sources of supply and choose  Adopt. If you select several sources of supply, the system automatically selects the best source of supply with regards to the ranking list criteria. The system creates the procurement proposal with the selected source of supply.
