 Stock Determination

 

You use stock determination to apply stock removal strategies during picking and stock transfers, based on predefined settings in Customizing. Based on the recorded product requirements, SAP Extended Warehouse Management (SAP EWM) determines in which sequence and from which storage types and stocks you should remove the desired product.

SAP EWM executes stock determination during creation of the warehouse task. In so doing, SAP EWM takes into account own stocks, consignment stocks, and, in the case of internal movements, different stock types.

Prerequisites

You have set stock determination groups in Customizing for SAP EWM under Start of the navigation path Cross-Process Settings Next navigation step Stock Determination Next navigation step Maintain Stock Determination Groups End of the navigation path, and have saved these groups in the master record so that SAP EWM can execute stock determination for a product.

You have made the settings in Customizing for SAP EWM under Start of the navigation path Cross-Process Settings Next navigation step Stock Determination Next navigation step Set Stock Determination End of the navigation path, for a stock determination strategy that the system uses to reduce stock. In so doing, you define a valuation to evaluate stocks of different owners or different stock types in a different manner.

Features

In SAP EWM, stock determination occurs in the background during creation of warehouse tasks.

You can define the following stock determination strategies:

  • Stock Determination Dominates

    During stock removal, SAP EWM considers the warehouse number stock characteristics Owner and Stock Type as defined by you. In doing so, it uses the stock removal sequence to check the existing stocks for the corresponding stock.

    The stock removal sequence arises from prioritizing individual stocks according to the valuation you have defined. SAP EWM first searches through existing stocks according to the stock characteristics that have the highest number of points. If the required stock is larger than the stock found, SAP EWM searches the existing stocks according to the stock characteristics that have the next highest number of points. SAP EWM continues this process until it finds enough stocks for the required stock, or it notifies you that it can only find a portion of the required stock.

  • SAP EWM Dominates

    During stock removal, SAP EWM considers all allowed stocks, regardless of the stock characteristic of the warehouse number. It stores the required quantities and in so doing, only takes into account the stock removal rule defined in SAP EWM, such as FIFO. In this case, SAP EWM removes the oldest quantity from stock, irrespective of whether this is an own stock or a consignment stock. You can also use the stock determination’s number of points as sort criteria in the stock removal rule, so that for example, the stocks found per storage type are removed from stock according to descending number of points.

Activities

In Customizing for SAP EWM under Start of the navigation path Cross-Process Settings Next navigation step Stock Determination Next navigation step Maintain Stock Determination Groups End of the navigation path, define the stock determination strategy (stock determination dominates or SAP EWM dominates).

Example

You define a stock determination strategy that you use during replenishment activities to firstly remove own stock (owner GLENN) and then to remove consigned stock for owner SCHMIDT (owner SCHMIDT). To do this, you define the following in Customizing for SAP EWM:

  • Maintain stock determination group

    You define the stock determination group 01 for warehouse 001, using the stock determination strategy Stock Determination Dominates.

  • Set stock determination

    Warehouse Number

The system uses your stock determination strategy to search for the stock determination group 01.

  • If you have defined the strategy Stock Determination Dominates for the stock determination group 01, SAP EWM first searches the warehouse for own stock according to the set stock removal strategy. If SAP EWM cannot fill the required quantity for the warehouse task, it also searches for stocks from owner SCHMIDT and uses stocks found here as well, to fill the warehouse task’s required quantity.

  • If you have defined the strategy SAP EWM Dominates for the stock determination group 01, SAP EWM searches the warehouse for own stock and for stock from owner SCHMIDT, according to the set stock removal strategy. You define the stock removal sequence by using the storage type search sequence and the stock removal strategy, such as FIFO. You have made settings in Customizing for stock determination to define valuation points for the individual owners, and thus have undertaken a prioritization. You can use this prioritization to sort stocks for a storage type or storage type group.
