Stock Placement — Near-Fixed Bin with Capacity
• Combination of strategies:Implement Capacity Check 3 for Fixed Bin Storage Type
Neutral Indicators per Bin and Material“Near-Fixed Bin” for Bulk and Rack Type MediasTogether, provide “top off” functionality in Fwd Pick Bins while making replenishment process more efficientOther considerations:
Palletization data (LE Quantity) from WM2 View (Material Master View) can help with this process for separate transfer order (TO) line items per material
10
Stock Placement — Near-Fixed Bin with Capacity (cont.)
• Maximum Fixed Bin Quantity of 40 cases
• One pallet is equal to 10 cases
• Current Fixed Bin Quantity is 34 cases
11
Stock Placement — Near-Fixed Bin with Capacity (cont.)
• Transfer order for 14 cases — it will first attempt to Putaway the pallet quantity of 10 cases and then the loose 4 cases

Stock Placement — Near-Fixed Bin with Capacity (cont.)
• For Line 1, 10 cases, the proposed Destination Bin is the Reserve Storage Type near the Fixed Picking Bin
13
Stock Placement — Near-Fixed Bin with Capacity (cont.)
• For Line 2, four cases, sufficient capacity is found in the Fixed Bin and is identified as the Destination Bin
14
Stock Removal — Large/Small Picking
• Large/Small PickingPick Strategy where the source storage bin for picking is decided upon based upon the size of the order quantity
• Dependent upon Master Data and Search Strategies for Removal
• Rounding Quantity setting is an option within configuration at Storage Type level

Wave Planning (cont.)
• Wave PickingVariation of Batch and Zone Picking; multiple zones picked at one time and later sorted and consolidated for final shipmentWorks well in operations with Low to High numbers of orders and Moderate to High picks per order
34
Wave Planning (cont.)
• SAP offers tools to handle all types of picking methods• Most common methods of manually creating waves are
through Outbound Delivery MonitorWave Planning According to Shipments also availableCreate by Delivery or Shipment Group Times
• Deliveries are assigned at the Header LevelA single delivery cannot be split to two separate waves
35
Wave Planning (cont.)
• A background batch job is run periodically to create waves of one or more deliveries. The batch job then creates transfer orders for picking.
• The waves are created based on criteria maintained in the Load Wave Creation Table
• The batch job is scheduled to run every hour• Hazardous and non-hazardous orders are split into two
separate deliveries. The deliveries can be waved together based on the parameter table.

Wave Planning (cont.)
• In certain situations, the user may need to trigger the batch job manually
Use transaction ZTOCREATE: Creates waves and generates transfer orders for parts shipping points
• The batch job will run as normal using the criteria from the parameters table
• The batch job will also still run at its normally scheduled time
• The following slides show an example of using standard functionality with a custom front end for wave creation along with SAPConsole
Grouping of deliveries and Zone Picking

What Is Cross-Docking?
• Distribution method in which the goods flow in an unbroken sequence from receiving to shipping (dispatching), thus eliminating storage. Also called flow-through distribution.
Source: The Business Dictionary• Cross-docking is the practice in logistics of unloading
materials from an incoming vehicle and loading these materials in outbound vehicles with little or no storage in between.
Source: Wikipedia.com
Planned Cross-Docking
• A decision that establishes a link between a Planning document and Candidate document prior to the actual arrival of incoming stock and release of an outbound delivery or requirement

Opportunistic Cross-Docking
• The system automatically designates a document or item for cross-docking after arrival of incoming stock of an outbound delivery or requirement
• A prerequisite is an open picking or putaway transfer order
• Does not override existing decisions, but will cancel open TOs
• With standard, only works in the form of one-step docking
72
73
Goals of Cross-Docking
• Enable planned and opportunistic cross-docking• Provide user-friendly interface for cross-dock planning
and monitoring• Evaluate utilization of cross-docking, considering the
following:Ensure cross-docking does not contradict warehouse rulesEstablish a method of communication between incoming stock and outgoing demand based on customer requirements and organizational goals
• Enable automatic and manual decision-making modes
74
Cross-Docking Overview
• Document types available for possible cross-docking decisions

Final Thoughts on Cross-Docking
• FIFO considerations are configurable• Cross-docking is integrated with SAP Yard Management
System (YMS)• Will not create a decision if the Load Quantity is greater
than the Open Decision QuantityConsider a BAdI for full or less-than-full pallet quantities
• Does not support Mixed Pallets• Applies to Available Stock only• Customer-specific requirements can be added
Exclude materialsModify algorithms for “optimal” cross-docking

7 Key Points to Take Home
• SAP Warehouse Management is a powerful, standard tool when completely configured and utilized in the warehouse
• The use of standard functionality with customized front or back ends can alleviate development efforts and future upgrade headaches
• SAPConsole is a mature product that will continue to be supported by SAP
• Task and Resource Management provides the ability for my warehouse to manage both resources and equipment together at a more detailed level than WM
125
7 Key Points to Take Home (cont.)
• SAP Yard Management can be activated to extend warehouse management-type actions beyond the four walls of the warehouse into my yard
• SAP Cross-Docking can reduce material handling costs in my warehouse by providing seamless, system-guided direction for cross-dock opportunities
• SCM Extended Warehouse Management is the future of SAP Warehouse Management; however, ERP WM will continue to be used and supported moving forward
