Informing SAP EWM about Requirements from Production

You use the standard SAP ERP functionality to trigger staging. SAP ERP creates outbound deliveries and sends them to SAP EWM.

Depending on the combination of storage locations in the SAP ERP control cycle, SAP EWM creates outbound delivery orders or posting changes.

You use the standard SAP ERP functionality to trigger staging. SAP ERP sends a message to SAP EWM. SAP EWM creates a PMR.

Overview

Not available

You can display an overview of the current stock on the production supply area (PSA) bin, the open warehouse tasks for this bin, and the current requirements for the product.

Quantities for Staging

The system uses the full quantity of a reservation item (pick parts) or multiple reservation items (release order parts) for staging. For more information, see SAP Note 91163.

The system creates a staging proposal based on the current stock on the PSA bin, the open warehouse tasks for this bin, and the current requirements for the product.

You can define how much of a product is to be staged at a time, for example, you always stage a full pallet.

You can also decide to stage a different quantity from quantity proposed by the system.

Planning Staging

You create warehouse tasks for the outbound delivery orders and posting changes that SAP EWM has created from the SAP ERP messages.

You create the warehouse tasks directly from the Staging for Production screen.

You can also schedule regular creation of warehouse tasks for staging for production using the report Schedule Staging for Production.

Staging per Order

You can use pick parts in SAP ERP to create a separate outbound delivery item for each manufacturing order. In SAP EWM, this item has a reference to the manufacturing order. You can see the manufacturing order number on your warehouse task and you can use it for printing.

After the warehouse task confirmation, the stock is not reserved for this order. You can use it for any manufacturing order.

You can use single-order staging to create warehouse tasks for each PMR separately. In this case, you can see the manufacturing order number on your warehouse task and you can use it for printing.

After the warehouse task confirmation, the stock is reserved for this PMR item. If you want to use the stock for another manufacturing order, you can release the stock.

If you need the product for this PMR item again after you have released it, you have to create and confirm a new warehouse task.

Collective Staging

You can use release order parts in SAP ERP to stage products for several manufacturing orders together. You create outbound deliveries for the cumulated quantity. These documents do not have a reference to the manufacturing order.

You can use cross-order staging to cumulate the quantities from several PMR items and supply the product for all of them together.

For cross-order staging, the stock is not reserved for a specific document.

Ad-hoc Staging

You can use all the functionality available in delivery-based production supply for staging products that are needed, but have not been planned.

You can use the transactions available in SAP EWM to move products which are not planned in a PMR to the PSA.

Not Relevant for Staging

Not supported

You can use the staging method not relevant for staging for products that are already on the PSA or for products that can be consumed from any goods issue bin.

If you want the system to determine the goods movement bin from the PSA, such as when you want to use exactly one bin for the goods movement, you can enter a storage bin in the settings for the PSA

If you do not enter a storage bin in the settings, you can enter a suitable storage bin at the goods issue.

Crate Parts

When you use crate parts in SAP EWM, it does not make a difference for staging which type of production integration you use.

Kanban

You can use the Kanban functionality in SAP ERP to create outbound delivery orders or posting changes in SAP EWM. These documents contain the Kanban number as reference document. You can use this number for printing in SAP EWM.

Not supported

Shuttle Process with Delivery Note

You can use a combination of an outbound delivery and an inbound delivery for your production supply. In the outbound delivery process, you can print a delivery note.

Not supported

Enter Consumption

You can use all the options available in SAP ERP to enter the consumption for an order, for example, transaction MIGO, or backflush. The system creates a consumption posting delivery in SAP EWM. The resulting outbound delivery order is not relevant for picking.

You can configure the system so that it posts the goods issue automatically when SAP EWM processes the message from SAP ERP.

For more information, see Consumption Posting Delivery for Production Supply.

You cannot enter a planned goods issue (with an update of the SAP ERP reservation) in SAP EWM. You can enter an unplanned goods issue for the order. This document does not update the reservation in SAP ERP. For more information, see Pickup and Account Assignment.

You can enter the goods issue in SAP EWM. When you post the goods issue, the system performs the following steps:

If you are not using the staging method single-order staging, you can also use all options for consumption available in delivery based production supply

Backflush

A consumption posting at production backflush works as described for consumption for delivery-based production supply.

When a material is set as backflush item in the manufacturing order, you cannot enter the goods issue in SAP EWM.

When you enter a backflush in SAP ERP, SAP ERP creates a consumption posting delivery, as described in consumption for delivery-based production supply. You can configure the system so that it adds the goods issue document to the respective PMR item as well as to the consumption posting delivery. You can use this functionality to have the same information for all items in the PMR.

You cannot use single-order staging for a material set as backflush item.

Crate Parts and No Staging

You can enter the goods issue in SAP ERP. The stock is provided in the production supply area as crate parts or it is permanently stored there, for example, a silo.

You can create PMRs for products where you want to use crate parts for staging or where you do not want to stage the product at all, for example, for silos. You can use the PMR to enter the goods issue in SAP EWM.

Integration with External Systems , for example, a legacy manufacturing execution system

SAP provides BAPIs as APIs for the connection to external systems in SAP ERP, for example, BAPI_GOODSMVT_CREATE. These BAPIs trigger the creation of an outbound delivery for an SAP EWM managed storage location. You can specify the stock on storage location level.

SAP provides an API for the goods issue and for goods issue cancellations in SAP EWM.

Separation of Stock

You can define in the control cycle which storage locations you want to use for the source stock in your warehouse and for your PSA. This provides the following options:

For more information, see Organizational Model for Production Supply.

In SAP EWM, you have to define the storage types and the stock determination strategies so that they fit to the data in the production supply delivery.

You must check the interaction with the availability check and the stock and batch determination in the manufacturing order for the organizational model.

You define one storage location in your SAP ERP control cycle. The system maps this storage location to a stock type in SAP EWM. This stock type is the stock type that the system expects for the goods issue. The stock type must be consistent with the availability group of the SAP EWM storage type for the PSA bin.

If you want to separate the responsibilities of the stock between warehouse and production, you can use different availability groups for the production supply storage type and the source storage type. The system sends a goods movement message to SAP ERP when the stock type of the stock changes. In SAP ERP, you can see the stock on storage location level to get an overview of the stock in the production supply area.

Performance

The system creates one delivery document for staging and one delivery document for each goods issue on the SAP ERP side. In SAP EWM you have two delivery documents for posting change (the posting change request and the posting change), or three delivery documents for outbound deliveries (the outbound delivery request, the outbound delivery order, and the outbound delivery).

The system creates one PMR per manufacturing order or, if you use components from more than one warehouse, one document per order and warehouse. There are no extra documents in SAP ERP, such as deliveries.

At a goods issue, the system sends a goods movement document to SAP ERP. SAP ERP posts the goods issue and does not create an outbound delivery.

System Maintenance

The production integration based on deliveries needs a tight integration between SAP ERP and SAP EWM. Both systems have to be available.

When you have a maintenance period in SAP ERP, you can continue to work on the PMRs that you have sent to SAP EWM before the maintenance period started.
