NEW GL document splitting

Question

Some documnt types like SA will not get split by documnt splitting functionality and some document types like cash posting will  get split according to the partner line items.....What are the functional reasons for not applying document splitting to few document types like SA. Also could you please list all the docment types that will not get split by new gl document splitting. And the account category types that will not get split.
Appreciate your response

Answer 1

It all depends on the configuration in the following nodes in SPRO.
Financial Accounting (New) -> General Ledger Accounting (New) -> Business Transactions -> Document Splitting -> Classify Document Types for Document Splitting
Financial Accounting (New) -> General Ledger Accounting (New) -> Business Transactions -> Document Splitting -> Classify G/L Accounts for Document Splitting
The reason (in standard config.) why document splitting does not happen for document type SA is because it is assigned to transaction 0000 (unspecified posting).  For transaction 0000, you would not see any item categories in splitting rule configuration.  That means, we are expected to give account assignment to each line item while posting using document type SA.
Again, this is standard configuration delivered by SAP for document splitting.  If it does not suit the business requirement, it can be changed.
Following is SAP's IMG Activity Documentation for the first node above.
Classify Document Types for Document Splitting
Every business transaction that is entered is analyzed during the document splitting process. In this process, the system determines which splitting rule is applied to the document. In order that the system can determine the splitting rule, you must assign a business transaction variant to each document type.
To ensure that a splitting rule is used appropriately, the relevant documents must meet certain requirements. These requirements relate in particular to certain item categories that either must or must not be available. This information is specified for each business transaction variant and is checked against the current document during posting. If the document does not meet these requirements, the system rejects the posting.
Example
The accounting transaction 0200 (customer invoice), variant 0001 (standard), is delivered. In this accounting transaction, the following item categories are allowed: customer, value added tax, withholding tax, expense, revenue, exchange rate differences, and company code clearing.
Standard settings
With the document types delivered in the standard system, SAP delivers a classification for document splitting. This classification is a proposal that you need to check against how your document types are organized. You need to check whether the classification or assignment to a business transaction variant produces the desired result in document splitting.
SAP includes business transactions in the standard system. The item categories that are allowed for each accounting transaction are also defined. Accounting transaction variants are also included. These are additional limitations of the accounting transaction.
You cannot define additional business transactions. However, you can define your own business transaction variants to the the standard business transactions.
Activities
Assign your document types to an accounting transaction and a business transaction variant.
Further notes
Document splitting is essentially controlled by the document type. You should therefore ensure that the documents used for business transactions are assigned uniquely in document splitting to a business transaction variant and in this way to a splitting rule.
You may therefore be required to introduce more document types.
Example:
The document type SA is assigned to business transaction 0000 Unspecified Posting with variant 0001.
In the methods delivered, no splitting rules are defined for the business transaction variant Unspecified Posting (with the exception of company code clearing). If an account assignment is expected in these documents, it has to be specified for all lines. This means that the system does not project any account assignments to non-assigned lines due to the absence of a splitting rule.
However, this document type is generally used for a large variety of business transactions that would also have to be treated differently in document splitting. In such cases, it is necessary to define additional document types and to assign them to the specific fiscal year variants.
