Use

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, Extended Warehouse Management (EWM) determines in which sequence and from which storage types and stocks you should remove the desired product.

EWM executes stock determination during creation of the warehouse task. In so doing, 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 EWM under Cross-Process Settings ® Stock Determination ® Maintain Stock Determination Groups, and have saved these groups in the master record so that EWM can execute stock determination for a product.

You have made the settings in Customizing for EWM under Cross-Process Settings ® Stock Determination ® Set Stock Determination, 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.

Note

For more information about Customizing for stock determination, see the Implementation Guide (IMG) for EWM under

Features

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

Stock Determination Strategies

You can define the following stock determination strategies:

Stock Determination Dominates

During stock removal, 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. 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, EWM searches the existing stocks according to the stock characteristics that have the next highest number of points. 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.

EWM Dominates

During stock removal, 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 EWM, such as FIFO. In this case, EWM removes the oldest quant 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 criterion 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 EWM under Cross-Process Settings ® Stock Determination ® Maintain Stock Determination Groups, define the stock determination strategy (stock determination dominates or 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 consignation stock for owner SCHMIDT (owner SCHMIDT). To do this, you define the following in Customizing for 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

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, EWM first searches the warehouse for own stock according to the set stock removal strategy. If 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 EWM Dominates for the stock determination group 01, 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.
