Material Staging

Purpose

You stage material you need for production at a certain time, in a particular quantity, and in a particular production storage bin, via the WM-PP interface.

Prerequisites

The WM-PP interface is active.

For automatic material staging, you must define a production scheduling profile in Customizing for Warehouse Management under Start of the navigation path Interfaces Next navigation step Define Production Define Control Data Production View End of the navigation path .

Process Flow

You create a production order in the application component Production Planning and Control (PP).

To display a production order, from the SAP menu choose Start of the navigation path Logistics Next navigation step Production Production Control Order Display End of the navigation path .

The component overview shows all of the components needed for the production order.

Menu Path from the Production Order Display screen	Result
Goto WM Pick List	The system displays: The production storage bin The material staging type The material quantity already requested
Functions WM Material Staging Proceed	The system executes material staging in the background, if you have released the production order first. To display processing errors, choose Goto Logs WM Material Staging Production Order Change .

Menu Path

from the Production Order Display screen

Result

Start of the navigation path Goto Next navigation step WM Pick List End of the navigation path

The system displays:

The production storage bin
The material staging type
The material quantity already requested

Start of the navigation path Functions Next navigation step WM Material Staging Proceed End of the navigation path

The system executes material staging in the background, if you have released the production order first.

To display processing errors, choose Start of the navigation path Goto Next navigation step Logs WM Material Staging Production Order Change End of the navigation path .

Release the production order in PP.
The system determines the material staging type on the basis of the control cycle and determines the production storage bins, in which the components should be staged.
Automatic material staging is active in the standard system. The Warehouse Management system (WMS) automatically creates the transfer requirements (TRs) needed for material staging.

You can also create transfer requirements for material staging manually.

Note Note

Transfer requirements for material staging have requirement type P, and the requirement number is equivalent to the number of the production order, for which the TR was created. For transfer requirements for crate parts or release order parts, the requirement number corresponds to the number of the assigned production supply area.

To display a TR for material staging, choose Start of the navigation path Logistics Next navigation step Logistics Execution Internal Whse Processes Transfer Requirement Display By Requirement End of the navigation path .

End of the note.

You create transfer orders for the staging TRs in the WMS.

You can also let the system create transfer orders (TOs) automatically. This means that the system automatically creates a TO for the material staging TR in the background. For more information, see Automatic Creation of TOs for Transfer Requirement.

You execute the physical staging of the material based on the transfer order and take the material to the production storage bin.
You post the goods issue for the material consumption.

There are two ways of posting the goods issue for the material consumption.

GI Posting for Material Consumption	What You Should Know
Backflushing with confirmation of the production order	With this kind of stock removal, the components are already at the production location. These are physically used up during the production process, but the consumption is not posted until the consumption quantity is known, that is to say after the order has been confirmed. You do not need to enter any goods movements in Inventory Management for these components. The production storage bin of the materials consumed is defined in the production order. The system reduces the material quantity in the production storage bin without creating a TR or a TO.
Manually in Inventory Management	After final assembly has been completed, you have to adjust the stock levels in Inventory Management and the Warehouse Management system to correspond to the current stock situation, and to reduce material consumption. Enter the production order number during GI posting.

GI Posting for Material Consumption

What You Should Know

Backflushing with confirmation of the production order

With this kind of stock removal, the components are already at the production location. These are physically used up during the production process, but the consumption is not posted until the consumption quantity is known, that is to say after the order has been confirmed. You do not need to enter any goods movements in Inventory Management for these components.

The production storage bin of the materials consumed is defined in the production order. The system reduces the material quantity in the production storage bin without creating a TR or a TO.

Manually in Inventory Management

After final assembly has been completed, you have to adjust the stock levels in Inventory Management and the Warehouse Management system to correspond to the current stock situation, and to reduce material consumption.

Enter the production order number during GI posting.

Note Note

If the WM-PP interface is not active, or if the production order or reservation was incorrectly updated due to a previous error, the system posts a the goods issue for the material consumption to a general interface, based on the source movement type 261 (in the standard system). In doing so, the system creates a transfer order.

End of the note.

Taking Into Account Changes in the Production Order

During material staging via the WM-PP interface, the system takes the following changes into account:

Changes in product quantities
Changes in assembly part quantities
Material changes
Changes to the work center
Technical completion of production order
Cancellation of technical completion
Change in storage location or plant
Change to batches (see Pick Parts)
Changes to dates/times

Example Example

The system cancels, for example, all superfluous transfer requirements (TRs) for pick parts, or triggers a follow-on request for missing quantities via a new TR.

End of the example.
