SAP IBP Location Master

Location Master is the SAP IBP master data type that represents every physical or organizational node in a supply network — plants, distribution centers, warehouses, cross-docks, customer sites, and vendor/supplier sites — as instances of a single, unified object. Unlike S/4HANA, which keeps Plant, Customer, and Vendor as three separate master data objects, SAP IBP collects and transforms all three into one Location record, differentiated only by a LocationType field (P = Plant, C = Customer, V = Vendor/supplier). This article maps what a Location record is, how its type dimension works, its place in the master data hierarchy, and the field-level detail of the Manage Locations app used to create, edit, and delete it.

Part 1: Location Master — Core Concepts (All Modules)#

1.1 What Is the Location Master?#

A Location record is not a schema definition — it is the actual master data instance that conforms to the Location Master Data Type (MDT-LOC, see IBP-A02-01). Every plant, distribution center, customer ship-to site, or vendor/supplier site that a planning model needs to reference must exist as a Location record before it can be used in a Planning Level, a Location Product, or a Location Source of Supply relationship. Location Master is classified as an Optional master in SAP IBP’s Phase 1 Master Data build — it is required only when a planning area plans by location; a pure product-and-customer demand plan, for example, may never need it.

1.2 Location Types#

SAP IBP does not model Plant, Customer, and Vendor as three separate master data objects the way S/4HANA does — it collects and transforms all three into a single Location record at integration time, and the LocationType field is the only thing that tells the planning model which real-world role a given Location plays. Assuming Plant, Customer, and Vendor remain separate objects when designing an integration model is a common early-project misunderstanding, since every downstream object (Location Product, Location Source of Supply, Planning Level) reads type-specific behavior off this one field.

Design principle: A Vendor-Managed Inventory (VMI) location generated from a customer-material info record is automatically created with LocationType P, not C — treat VMI locations as a plant-type exception, not a customer-type pattern, when validating integration results.

1.3 Organizational Levels and Data Hierarchy#

Data hierarchy with a concrete example

Client (SAP IBP tenant / Model)
   │
   ├── Master Data Type "MDT-LOC" — Simple · Location             (Zone A — see IBP-A02-01)
   │      └── Attribute "ATTR-REGION" — Region (NVARCHAR)           (Zone A — see IBP-A02-02)
   │
   └── Location Master (instances, Zone B)
          ├── Location "LOC-JP01" — Tokyo Plant, LocationType P (Plant)
          │      LOC-JP01 ── conforms to ──> MDT-LOC
          └── Location "LOC-JP02" — Osaka DC, LocationType P (Plant, node type DC)
                 LOC-JP02 ── conforms to ──> MDT-LOC

Design principle: Location sits in Zone B (Master Data Instances) as a concrete record conforming to the MDT-LOC schema defined in Zone A — the same client-tenant relationship every Simple Master Data Type’s instances follow (see IBP-A02-01 Section 1.3 for the schema-level view of Zone A). Because Location ID must be globally unique across all three Location Types, a Customer location and a Plant location can never share the same ID even though LOC-JP01 and LOC-JP02 above are both Plant-type — flag this integration model design constraint during blueprint.

1.4 Integration with Other Master Data Objects#

Location Master does not stand alone — it is both a consumer (it conforms to Master Data Type and reads calendar/region detail through Attribute) and a foundation (nearly every downstream planning object that needs a location dimension is built on top of it).

Part 2: IBP-Specific Field Details#

2.0 Scope of IBP Ownership#

Legend: ◎ = Owner / Critical, ○ = Direct involvement

2.1 General Location Identification & Type#

Every Location record — regardless of which real-world role it plays — starts from the same identification fields, whether entered manually in the Manage Locations app or populated automatically by master data integration from S/4HANA.

2.2 Basic Data#

Basic data fields describe the Location in business terms. For integrated Locations, these fields are collected and transformed from the source Plant/Customer/Vendor master rather than typed manually — manual entry is typically reserved for sandbox models or Locations with no S/4HANA counterpart.

2.3 Calendar & Attribute Assignment#

Location Master does not carry a dedicated calendar-type field in its base schema. Calendar and region grouping are both implemented through the same generic Attribute mechanism already covered in IBP-A02-02 — this section only cross-references how that mechanism applies specifically to Location, rather than re-explaining Attribute configuration itself.

2.4 Integration & Source System Mapping#

Location Master records are, in practice, most often created and kept current by master data integration from S/4HANA rather than manual entry — understanding the scoping and transfer mechanics is central to troubleshooting missing or stale Location data.

2.5 Downstream Consumption#

Once created, a Location record becomes the reusable building block that several downstream planning objects reference — this section maps what those objects are, without duplicating their own field-level detail.
