  • Slotting execution and results interpretation
  • Common issues in the use of slotting in SAP EWM and their resolutions
Key Concept
Slotting is a special feature provided by SAP Extended Warehouse Management (EWM) that does not exist in Warehouse Management (WM). It helps in optimal storage bin determination and forms the basis of optimizing the arrangement of products in the warehouse.

Slotting in SAP Extended Warehouse Management (EWM) is the process of putting goods in a warehouse in a way that ensures the most appropriate storage and picking of goods. Slotting uses a variety of data to determine suitable optimal putaway control parameters. These parameters describe the storage section in which the product is to be stored, the properties that the storage bin is to have, and the putaway strategy that is to be used. These parameters are listed below:

  1. Product master
  2. Storage requirement data
  3. Packaging data
  4. Demand forecast data

Slotting helps in determining the most optimal putaway parameters that ensure placement of goods in suitable bins in the warehouse. It determines suitable putaway parameters such as storage type, storage section, and bin type for placement of goods.

Configuration Steps for Slotting

To use slotting in EWM, you first need to configure related objects. This process requires you to complete seven steps as shown in Figure 1.

Step 1. Create a Condition Table

Condition tables are used for different applications, for example, packaging specification determination, printing warehouse orders, and slotting. In this article I explain how to create a condition table for slotting.

In a condition table you specify the combination of fields that should form the individual condition record. The number of fields used for a condition table is limited to 10. In the example discussed in this article, I have selected two fields, Warehouse Number and Warehouse Product Group, to form condition records. These fields are used later in the article for Condition Record Maintenance.

To create a new condition table in EWM execute transaction code SPRO and follow menu path Extended Warehouse Management > Good Receipt Process > Slotting > Condition Technique > Condition Table > Edit Condition Table for Putaway Control Indicator.

In the screen that appears, enter the name of the Condition Table (ZCON_TAB) and a Description (Condition Table for Putaway Control). Select the CONLG_NUM and CON_MATGNR fields from the list of available fields and move them to the right by clicking the arrow button highlighted in yellow as shown in Figure 2.

Note
The condition table can contain as many fields as needed. For my example, select fields for Warehouse Number and Warehouse Product Group.

In the same screen, you can see both the fields are now available on the right side (Figure 3). Save and activate the table by clicking the activate icon and then clicking the save icon.
