What’s inside a DaRT 2.7 extract: a guide to the segments
A SAP DaRT 2.7 extract does not arrive as a flat file. It contains a structured collection of named segments — each one corresponding to a specific table or view from the SAP system. Before you can work with the data, it helps to understand which segments exist, what they contain, and how they relate to the modules you care about.
This post gives an overview of the 280 segments in a DaRT 2.7 extract. At the end you will find a link to an interactive reference where you can browse and search all of them.
What is a segment?
In a DaRT extract, a segment is a data block. It is described by other segments that contain its name, its field names and its field types. There are even segments that describe unique key constraints and referential constraints. The segment name often hints at the SAP module and data it covers, but rarely matches an SAP table name directly. A segment typically contains a subset of a table’s fields, and sometimes combines fields from multiple SAP tables. For example, TXW_FI_HD contains FI document header data, and TXW_MM_POH contains MM purchase order headers.
This self-describing nature is one of the strengths of the format: you do not need a separate data dictionary to understand what a field contains. It also makes data acquisition much safer than reading CSV files because there is no ambiguity about field types.
The modules covered
DaRT 2.7 extracts data from eleven SAP application areas. Here is a brief overview of each:
- FI — Financial Accounting. The core of most tax analyses. Contains GL document headers and line items, open items, account balances, customer and vendor master data, tax codes, payment terms, and chart of accounts structures. This is where you find every posted document.
- CO — Controlling. Cost centers, profit centers, internal orders, cost elements, and project structures. Essential for allocation analysis and transfer pricing.
- MM — Materials Management. Purchase orders, goods movements, material master data, vendor information, and inventory valuation. Relevant for input VAT, customs, and supply chain analytics.
- SD — Sales & Distribution. Sales orders, delivery documents, billing documents, pricing conditions, and customer master sales data. The counterpart to MM for output VAT and revenue analysis.
- AM — Asset Accounting. Asset classes, depreciation keys, depreciation areas, and asset transaction types. Relevant for capital expenditure review and trade tax.
- TR — Treasury. Financial transaction types, portfolio positions, and valuation customizing for financial instruments.
- RE — Real Estate. Rental objects, real estate contracts, measurement types, and partner data for the RE-FX component.
- TV — Travel Management. Travel expense types and trip classifications.
- JV — Joint Venture. Business transactions and purchasing document categories for joint venture accounting.
- CL — Loans Management. Reference interest tables, collateral types, and calculation bases for loan products.
- Cross-Application. Segments shared across modules: countries, currencies, quantity units, address management, condition types, and valuation areas.
What is not in this reference
A small number of segments in the raw DaRT format carry SAP system metadata rather than business data — things like ABAP domain values, logical system descriptions, authorization group definitions, and transaction text tables. These have been excluded from the reference below, as they are not useful for tax or financial analytics.
