Using the quantity offsetting function, you can offset quantities consistently independently of the application.
In delivery processing, you use the quantity offsetting to calculate the open quantities for a document or to calculate the relevant quantities (requested quantity and reduced quantity) for checking a document execution, for example. This means that you can check whether you actually delivered the agreed quantity on a certain date.
The quantity offsetting is a cross-application service within Logistics.
The quantity offsetting is executed at item level and at schedule line level of a document. At present, the schedule line level is not supported by the documents in delivery processing.
Quantity offsetting consists of the following features:
Quantity type
Quantity calculation
Quantity offsetting
Quantity role
Quantity offsetting profile
The quantity type is a classification of the different quantities for quantity offsetting.
Examples of quantity types include:
Requested quantity
Reduced quantity
Open quantity
The quantity calculation determines the mathematical function (quantity calculation rule) for calculating the relevant data for quantity offsetting. You therefore define how the reduced quantity of a document is determined and which algorithm is to be used to calculate this quantity, for example. The relevant data for the quantity calculation algorithm comes from either the document flow or from a different source (from a service, for example).
If you use the document flow for the quantity calculation algorithm, you have to define which links are relevant in Customizing for delivery processing.
Example
The data in Handling Unit Management (HUM) is used for the packed quantity.
The quantity offsetting determines the function (quantity offsetting rule) with which the different quantities are calculated.
Depending on how it is used, you can access the quantity offsetting with or without quantity calculation.
The quantity role is used to group quantity calculation or quantity offsetting rules for certain applications or processes. In this way, you can define the quantity calculation or quantity offsetting rules according to the application or the process.
A quantity role can exist of several quantity types.
If you want to execute quantity offsetting automatically, a quantity offsetting profile exists in the quantity offsetting. This profile contains the quantity calculation and quantity offsetting rules to be used by the quantity offsetting to calculate the quantities automatically. The quantity offsetting profile is linked to the document type and item type of a document.
SAP delivers predefined quantity offsetting profiles types for the standard processes in delivery processing.
