What the badges mean

Active

Active and unchanged in S/4HANA.

Deprecated

Still readable today, but no longer SAP's strategic path — plan around it.

Replaced

Replaced by a new persistence in S/4HANA; the classic name may still answer reads (see read mechanism).

Migrating to IBP

Planning scope is moving from APO toward IBP.

Active (StRM) · Replaced (EWM)

Path-dependent: active with SAP Stock Room Management, replaced where EWM is the warehouse path.

Replaced · Compat View

Compatibility view: the classic table name is redirected to a view over the new persistence — see how the physical model moved.

Active · Proxy View

Proxy view: reads route through NSDM proxy/CDS views — see how the physical model moved.

master

Data class: what the table holds — master data, transaction documents, org structure, config, or texts (one row per language — see the quirks guide).

Linked type codes

CLNT — the client key; filter it explicitly and carry it through every join.

NUMC — fixed-width numeric text; keep it a string and keep the leading zeros.

DATS, TIMS — character date (YYYYMMDD) and time (HHMMSS), zero-filled when initial.

CURR, CUKY, QUAN, UNIT — amounts and quantities, meaningful only beside the currency key or unit that qualifies them.

LANG — a language key in a text table — one row per language.

In field listings, K marks a primary-key field, and linked type codes in the Type column jump to the matching quirks-guide section.

Fields

7 fields · 5 key

The join key is all 5 key fields together — matching on any single one fans out. See composite keys in the quirks guide.

7 fields.

Table fields: key flag, field name, description, data type (linked to the data quirks guide where the type carries a known trap), length, and check-table references. 7 fields.
Key	Field	Description	Type	Length
Primary key	MANDT	Client	CLNT	3
Primary key	STLTY	BOM Category	CHAR	1
Primary key	STLNR	Bill of Material	CHAR	8
Primary key	STLAL	Alternative BOM	CHAR	2
Primary key	STKOZ	Internal counter	NUMC	8
	BMENG	Base Quantity	QUAN	13,3
	BMEIN	Base Unit of Measure	UNIT	3

Linked type codes in the Type column jump to the matching section of the SAP data quirks guide.

Field provenance: hand-curated.
