Evaluations for Work-in-Process (WIP) Stock

Use

Work-in-process (WIP) stocks are stocks of components or unfinished products that are waiting at a resource for further processing. Quantities and queue times are important indicators for assessing the quality of the schedule in relation to costs and the lead times for orders .

The following evaluations are available for the WIP in the order and resource evaluations and in the DS planning board :

Evaluations for WIP stock

Evaluation

Description

WIP list

This evaluation shows order-internal WIP stock for the order product for selected resources. You use this evaluation if the order product is passed on, on behalf of one operation to another, whereby the total quantity is passed on or is needed at once (that is, there is an availability date or a requirement date per operation).

The following is displayed for each operation at the selected resources:

The quantity of the unfinished main product in the order, which is provided by the preceding operation in the order and which is waiting for further processing.
As WIP queue time: The time between the availability date and the requirement date. The queue time is negative if the availability date lies after the requirement date.

For operations with continuous input or output you cannot use this evaluation. Here you use the Enhanced View of the evaluation WIP list (network).

WIP list (network)

This evaluation shows the WIP stock for components for selected resources that are provided by other orders.

The following is displayed as a default for each operation at the selected resources:

As the WIP quantity: The total quantity of a component provided by operations from other orders and waiting for further processing
As the WIP queue time: The time between the availability date for the total quantity and the earliest requirement date for the component

The queue time is negative if the availability date lies after the requirement date. The system calculates using this evaluation for short queue times,

If several orders deliver an operation or if an order produces a component continuously (because the system calculates using the availability date for the total quantity)
If an order delivers several operations or if an operation uses the component continuously (for the system calculates using the earliest requirements date)

For this evaluation you should therefore choose Enhanced View. . Here

the total quantity is broken down into the supplying orders
the individual WIP queue time is displayed for each single quantity
WIP stock for operations with continuous input or output is evaluated in more detail

Note Note

The system displays the WIP data in the SAP List Viewer. Note: In the Enhanced view , you can only use the summation function of the SAP List Viewer effectively for WIP quantities. The summation function provides the sum of the individual queue times for the WIP queue times, instead of the more generally required sum of the queue times weighted by the individual quantities.

End of the note.
