 Service Loss Category: Stock Difference

Use

The service loss reasons belonging to the service loss category Stock Difference define that errors have occurred in Extended Warehouse Management (EWM). An error in warehouse management can, for example, be the introduction of a negative stock difference following a physical inventory count.

The quantity that can be assigned to these service loss reasons is limited to the sum of all negative stock differences.

Prerequisites

  • In Customizing for EWM, you have defined the physical inventory area of the warehouse and set the physical inventory process.

Features

The following service loss reasons belong to the service loss category Stock Difference .

  • Negative Stock Difference

    This service loss reason defines that a negative stock difference has occurred at the first stockholding location, for example, because of a physical inventory count.

  • Negative stock difference at contract packager

    This service loss reason defines that at least one contract packager has introduced a negative stock difference at the first stockholding location.

Activities

Service loss analysis calculates the throughput time for each customer-requested schedule line for which one of the service loss reasons belonging to this service loss category is checked. The throughput time is calculated from the first stockholding location to the main supplier (backwards from the service loss reference date/time).

The system selects all negative stock differences of the customer-requested product (which have led to a reduction in the available stock) that occurred at the stockholding location during the throughput time.
