SAP comes delivered with a number of ‘Document Types,’ which are used in various postings. The document type helps to classify an accounting transaction within the system, and is used to control the entire transaction and determine the account types a particular document type can post to. For example, the document type ‘AB’ allows you to post to all the accounts, whereas type ‘DZ’ allows you to post only the customer payments. Every document type is assigned a number range.
The common document types include:
| Document Type | Description | Document Type | Description |
|---|---|---|---|
| AA | Asset posting | KG | Vendor credit memo |
| AB | Accounting document | KN | Net vendors |
| AF | Depreciation postings | KR | Vendor invoice |
| DG | Customer credit memo | KZ | Vendor payment |
| DR | Customer invoice | KG | Vendor credit memo |
| DZ | Customer payment | SA | GL account document |
| X1 | Recurring entry doc. | X2 | Sample document |
Transaction Code to Define Document Type is OBA7 and to change it OBAB.
