Document Splitting Rule

Defines for a business transaction which item categories the system splits and from which item categories the system derives the account assignments for the document splitting characteristics defined.

With this object, you can define active document splitting for a business transaction and a business transaction variant.

Structure

A document splitting rule is assigned to a document splitting method and defines document splitting for a business transaction and a business transaction variant. You can copy a document splitting rule and assign it to a customer-defined document splitting method.

The document splitting rules are based on the item categories that are assigned to the accounts. You define which item categories the system splits and from which item categories the system derives the account assignments for the document splitting characteristics defined. The item categories valid for a business transaction are defined by the business transaction variant assigned.

The definition of a document splitting rule is divided into the following hierarchy levels:

Header Data

You can make the following settings in the header data:

Deactivate account assignment inheritance or standard account assignment
If you have activated the account assignment inheritance or the standard account assignment in document splitting, you can deactivate them for the business transaction and the business transaction variant assigned. For more information, see Enhancement Logic.
Assign account key for zero balance setting
If you use document splitting characteristics with a zero balance, you can define for the zero balance clearing one of the account keys that you have created in Customizing for Document Splitting under Define Zero-Balance Clearing Account . If the balance of the account assignment objects concerned is not zero after document splitting, the system creates additional clearing line items and posts the items triggered in the document to the specified zero-balance clearing account.
Define leading item for cross-company code transactions
A cross-company code posting creates at least two documents that you can process in document splitting as follows:
- Split each document in each company code separately
  In this case, do not enter a leading item category. You can only use one entry of item category Company Code Clearing (01100) for the item category to be processed. The system displays this entry in the list of item categories to be processed as follows: 01100 — Company Code Clearing — CoCode <> CoCode of Leading Item. During processing, the system only considers item categories relating to the company code currently being processed.
- Process all documents together as one cross-company code document
  In this case, you define the leading item category. You create two entries of item category Company Code Clearing (01100) for the item category to be processed. The system displays these entries in the list of item categories to be processed as follows:
  - 01100 — Company Code Clearing — CoCode = CoCode of Leading Item
  - 01100 — Company Code Clearing — CoCode <> CoCode of Leading Item
  The system first processes the documents that do not contain the leading item category. In the company code clearing item of the document, the split is based on the local document.
  
  The system then processes the document containing the leading item. The system splits this document on the basis of the local documents.

Note Note

In SAP systems, there needs to be a 1:1 assignment between company codes and companies. The system uses the affiliated company to find the connection between the company code clearing items of the company code of the leading item and the company code clearing items of the non-leading items.
The system does not use accounts to derive item category 01100. The technical prerequisites need to be fulfilled for internal derivation.
In the case of document splitting characteristics that depend on controlling areas, such as profit centers, the company codes involved must be assigned to the same controlling area. Otherwise, cross-company code projection is not possible.

End of the note.

Item Categories to Be Processed

In the list of item categories to be processed, you define which item categories the system splits. This list must contain all item categories that do not have account assignments in the entry view of the document. Given that a business transaction can contain different business processes (for example, the business transaction Customer Invoice contains the business processes Invoice and Credit Memo), the document splitting rule must define the item categories to be processed for all of the business processes involved. For more information, see Business Transaction.

In most cases, you define the basis item categories for the item catetory to be processed, from which the system derives the account assignments. However, you can also use the processing category of the category item to be processed to specify that the system transfers a fixed value as the standard account assignment. In this case, a constant that determines the account assignment needs to be defined in Customizing for Document Splitting.

Basis Item Categories

With the basis item categories, you define from which item categories the system derives the account assignments for the item catetory to be processed.

When processing a document, the system only considers basis item categories that exist in the document to be split.

You can specify that the system only considers a basis item category if passive document splitting has derived its account assignments from a preceding document. To do this, set the Split Automatically indicator. You must set this indicator if the basis item category has the same item category as the item category to be processed. This is the case, for example, with a transfer posting from a customer to another customer.

Interpretation of Document Splitting Rule

The system processes the document splitting rules as follows:

The list of item categories to be processed from bottom to top
The list of basis item categories for the current item category to be processed from bottom to top

As soon as the system can determine the account assignments for an item category to be processed from one of the basis item categories, it continues with the next item category to be processed until all of the item categories to be processed have been processed.
