S/4HANA Database Tables for Products, Material, and Equipment
In SAP S/4HANA, managing products, materials, and equipment involves various database tables that store detailed information about these entities. Understanding the hierarchy and relationships between these tables is crucial for effectively managing and accessing this data.
1. Overview of Key Tables
1.1 Material Master Tables
Material Master data is central to many business processes in SAP, including procurement, inventory management, and production. The main tables include:
- MARA (General Material Data): Stores general data about materials, such as material type and industry sector.
- MAKT (Material Descriptions): Contains material descriptions in various languages.
- MARC (Plant Data for Material): Stores plant-specific data for materials.
- MBEW (Material Valuation): Contains valuation data for materials at the plant level.
- MVKE (Sales Data for Material): Stores sales-specific data for materials.
- MARD (Storage Location Data for Material): Contains data about material quantities at storage locations.
- MAW1 (Material Master: Warehouse Number Data): Stores warehouse-specific data.
1.2 Product and Equipment Tables
Product and equipment data in SAP S/4HANA is closely related to the Material Master but includes additional tables:
- EQUI (Equipment Master Data): Contains data about individual pieces of equipment.
- EQST (Equipment to BOM Link): Links equipment to Bill of Materials (BOM).
- EQKT (Equipment Short Texts): Stores short descriptions for equipment.
- IFLOT (Functional Location): Stores data about functional locations, which are hierarchical structures used to manage equipment.
2. Hierarchical Relationships Between Tables
The relationships between these tables form a complex hierarchy, with the Material Master at the core, linking to various other tables for plant-specific, sales-specific, and storage-specific data.
2.1 Material Master Table Relationships
- MARA (General Material Data) is the central table and links to other tables:
- MARC (Plant Data for Material) via
MATNR
(Material Number) andWERKS
(Plant). - MAKT (Material Descriptions) via
MATNR
andSPRAS
(Language Key). - MBEW (Material Valuation) via
MATNR
andBWKEY
(Valuation Area). - MVKE (Sales Data for Material) via
MATNR
andVKORG
(Sales Organization). - MARD (Storage Location Data for Material) via
MATNR
andLGORT
(Storage Location).
- MARC (Plant Data for Material) via
2.2 Equipment and Functional Location Relationships
- EQUI (Equipment Master Data) is linked to:
- EQST (Equipment to BOM Link) via
EQUNR
(Equipment Number). - EQKT (Equipment Short Texts) via
EQUNR
. - IFLOT (Functional Location) via
TPLNR
(Functional Location Number).
- EQST (Equipment to BOM Link) via

3. Important Table Relationships
3.1 MARA and Related Tables
- MARA-MATNR (Material Number) is the primary key that connects to
MARC
,MAKT
,MBEW
,MVKE
, andMARD
. - MARC-WERKS (Plant) connects material data to specific plants.
- MAKT-SPRAS (Language Key) allows material descriptions in multiple languages.
3.2 EQUI and Related Tables
- EQUI-EQUNR (Equipment Number) is the key for linking to
EQST
andEQKT
. - IFLOT-TPLNR (Functional Location Number) links equipment to its functional location.
4. Example Queries
4.1 Retrieve Material Information with Plant Data
SELECT * FROM mara
INNER JOIN marc ON mara~matnr = marc~matnr
WHERE mara~matnr = 'MAT001'.
4.2 Retrieve Equipment and Related BOM Information
SELECT * FROM equi
INNER JOIN eqst ON equi~equnr = eqst~equnr
WHERE equi~equnr = 'EQ001'.
Conclusion
Understanding the hierarchy and relationships between these S/4HANA database tables is essential for effectively managing and retrieving data related to products, materials, and equipment. This knowledge enables developers and analysts to write efficient queries and build robust applications that interact seamlessly with SAP's complex data structure.
