2. Cross Docking
Reasons for Cross-Docking
If you aim to process products and handling units (HUs) as efficiently as possible,
and to minimize unnecessary load transfer activities in the warehouse, you can use
a cross-docking process in a distribution center or warehouse. Cross-docking is
the practice of unloading materials from an incoming vehicle and loading these
materials directly into outbound vehicles, with little or no storage in between.
Reducing the time in storage in the warehouse enables you to reduce stockholding
costs
Warehouse space is expensive and keeping too much material in stock is dead
equity. Only materials that are difficult to get should be kept in stock and,
whenever possible, material should be unloaded and sent directly to customers
or into production.

Cross-Docking Possibilities in EWM
There are several possibilities in EWM for cross-docking. First you have to
distinguish between planned cross-docking and opportunistic cross-docking.
5. Cross docking
Planned Cross-Docking
In planned cross-docking, you define in Customizing how the cross-docking
process is to proceed. The cross-docking relevance is therefore already defined
before stock arrives, and before you post goods receipt or release the outbound
delivery.
Opportunistic Cross-Docking
In opportunistic cross-docking, you first work with standard inbound and
outbound deliveries and start the standard goods receipt process or goods issue
process. You determine the cross-docking relevance after the goods have entered
the warehouse or before they leave it.
Push deployment (PD) and Pick from goods receipt (PFGR)
Push deployment (PD) and pick from goods receipt (PFGR) are opportunistic
cross-docking processes, When you post goods receipt, Extended Warehouse
Management (EWM) checks whether the warehouse process type and stock
type are relevant for putaway delay. If they are relevant, EWM starts the
putaway delay. As a result, EWM would delay the automatic generation
of the warehouse tasks for the putaway initiated via PPF. SAP Advanced
Planning & Optimization (SAP APO) defines whether an inbound delivery
is PD-relevant or PFGR-relevant. This means that SAP APO defines the
cross-docking relevance after posting goods receipt.

Prerequisite:
You have a system landscape in which you are using SAP EWM, SAP APO,
and SAP Customer Relationship Management (SAP CRM).
– Push deployment (PD)
You use PD so that you can react to requirement changes and requirement bottlenecks in
your warehouse quickly and flexibly. You can use PD to execute stock transfers for
delivered products from one warehouse to another at short notice, without having to put
away the goods.
– Pick from goods receipt (PFGR)
In PFGR, you can confirm a sales order that is not yet confirmed via the ATP check by
posting goods receipt for an inbound delivery. You can perform this picking from directly
within the goods receipt area; unlike the standard pick procedure, you do not have to put
away the products.
EWM-triggered opportunistic cross-docking
This process takes place entirely in Extended Warehouse Management (EWM). When
EWM generates putaway or pick-warehouse tasks, it defines whether opportunistic cross-
docking is to take place, that is, whether the inbound delivery or outbound delivery order
item is relevant for cross-docking. You can activate this cross-docking procedure for the
inbound and outbound delivery process separately at warehouse or product level.

EWM-Triggered Cross-Docking in the Inbound Delivery Process
Extended Warehouse Management defines whether the inbound delivery is
relevant for cross-docking. You can use this process when you generate warehouse
tasks for the putaway. EWM then checks whether the inbound delivery suits an
existing outbound delivery order item in terms of the following criteria:
• Product
• Batch
• Quantity including stock separation characteristics, such as party entitled
to dispose or the sales order stock
In this case, you can take the stock directly from goods receipt to goods issue. The
process can be performed with or without storage control.

Steps for EWM Triggered crossdocking
1) Activate EWM-triggered opportunistic cross-docking for your warehouse
number .
In the IMG of your EWM system, choose Extended Warehouse Management → Cross-Process Settings
→ Cross-Docking (CD)→ Opportunistic Cross-Docking → EWM-triggered opportunistic
Cross-Docking → Activate EWM-triggered opportunistic Cross-Docking.
2) Maintain the Product Group Type CD and the Product Group Cross Docking
a) In the Easy Access menu of your EWM system, choose Extended Warehouse Management →
Master Data → Product → Maintain Product.
3) Create stock determination group . For the Inbound Value F2 and the Permitted
Value F1 the Valuation 10 shall be assigned.
In the IMG of your EWM system, choose Extended Warehouse Management → Cross-Process Settings
→ Stock Determination→ Maintain Stock Determination Groups → Maintain Stock Determination
Groups.
4) In the IMG of your EWM system, choose Extended Warehouse Management → Cross-Process
Settings → Stock Determination→ Maintain Stock Determination Groups → Configure Stock
Determination.
5) Maintain the Stock Determination Group CD in the warehouse product.
6)Add the storage type 9010 in the storage type search sequence PICK in
your warehouse number.
11. Cross docking
Inbound driven Process:
1) Create Inbound delivery
2) GR+SAVE (don’t create any warehouse task now)
3) Create outbound delivery (create warehouse task check the source and destination bin, don’t save
it )
4) The GOTO the inbound delivery start creating putaway task
5) Then outbound picking status will be completed
6) Post GI in EWM
Outbound driven
6) Create Outbound deliver y (don’t pick) and then
7) Create Inbound delivery
8) Do GR
9) Create Pick task now

Transportation Cross-Docking
The decision to use transportation cross-docking is made by
EWM during the route determination of the outbound delivery
order.
For this, special routes called "cross-docking routes" are required.
The EWM route determination determines all suitable routes
between the starting point and the destination (which can be a
customer or another warehouse).
The result can either be a linear route, which is direct, or a cross-
docking route. A cross-docking route may be faster than a linear
route; for example, the linear route may depart very rarely, while
the cross-docking route leaves every day.
