A business transaction is depicted by a posting in accounting as one whole entity that can be reversed. It must be possible to uniquely identify the representation of a given business transaction in accounting.
On the basis of the specified document type, the system determines the business transaction that is represented by a posting. The business transaction uses the business transaction variant to control how the document is split. You assign a business transaction and a business transaction variant to a document type. You do this in Customizing for document splitting under
Classify Document Types for Document Splitting.
The business transaction variant is made up of item categories: An item category classifies a line item for document splitting. An example of an item category would be customer line. If you define your own rules for document splitting, these rules are based on item categories.
In the SAP standard delivery, document splitting contains various business transactions together with a respective standard business transaction variant (variant 0001 Standard). The business transaction variants in the standard delivery contain the maximum number of item categories. You cannot create your own business transactions. However, you can define – for each business transaction – your own business transaction variants to restrict the number of item categories. You do this in Customizing for document splitting under.
When you define a business transaction variant, you also have to define the relevant splitting rules. You do this in Customizing for document splitting under.
