 Example of Differentiation of Difference Type


This example shows how the system can differentiate between differences in value only and differences in quantity and value between an internal invoice and a self-billing document.

It does so using item category assignment.

Starting point

Doc. type of order (scheduling agreement) LZ

Item category LZN

Doc. type of delivery: LF

Doc. type of delivery-related initial invoice: F2

Note Note

The initial invoice is the invoice used to settle the LF delivery for the LZ scheduling agreement.

End of the note.

New item categories for value-only items:

SAP has shipped two new SD item categories as examples for value-only items in credit/debit memos: G2WT and L2WT (based on the standard item categories G2N and L2N.) The most important parameters in these item categories are:

Order item category for value-only items (in self-billing doc.) G2WT

Item type: A (value item)

Billing relevance: Order-related billing document.

Item category assignment

End of the note.

Since the two order document types G2WT and L2WT are new, settings must be made for them in Customizing for item category assignment (see also Customizing Checklist for Automatic Postings .)

The following entries have been made as an example:

Sales doc. type

Item category group

Item usage


Item category







If a credit or debit memo request is created with document type G2WT or L2WT and the corresponding material is controlled by item category group NORM, the system automatically determines the new item category for a value-only item.

If you have detailed differentiations (such as further item category groups) you must also make the approriate entries and assign the item categories G2WT and L2WT for these. You must set all item category determinations so that the document types G2WT and L2WT all lead to item categories G2WT and L2WT.
