Align safety stock, service targets, and replenishment logic inside SAP.
GIB Inventory is the inventory control layer for SAP ECC and SAP S/4HANA. It analyzes historical material movements to calculate stock, consumption, and variability metrics, classifies materials based on value and demand variability, and assigns MRP and service level logic systematically. Instead of relying on static master data settings, planners can evaluate coverage against replenishment lead time, simulate parameter changes before execution, and apply approved updates directly within SAP.

Establish Inventory Transparency

GIB analyzes SAP material document history (movement data) to build statistically accurate inventory key figures across defined time horizons. Metrics such as stock value, average stock, slow movers, dead stock, and consumption variability are calculated directly from historical movements.Instead of reviewing what inventory looks like today, planners see how inventory behaves across plants, MRP areas, and Controlling Groups over time. Controlling Groups are categorically unique material groupings where different MRP strategies can be applied. These groupings are defined using different combinations of SAP material master fields and can vary by plant.

Classify Materials Based on Value, Variability, and Lifecycle

Through ABC, XYZ, and Product Life Cycle (LRODI) classification, GIB segments materials based on consumption value, demand regularity, and lifecycle stage. Classification logic is maintained centrally and applied consistently across plants or Controlling Groups.
Planning strategies are then aligned to these classifications. For example, stable high-volume materials follow different safety stock and replenishment logic than irregular or slow-moving items. This prevents uniform planning rules from creating excess inventory or service risk.
-
Set MRP and Service Levels by Material Classification

GIB allows you to assign MRP parameters and service levels based on ABC/XYZ classification and Controlling Group.
Instead of changing safety stock, MRP type, lot size, or service level one material at a time, you define the rules once in the GIB MRP Parameters matrix and GIB Service Level matrix. For example, A/X materials can follow one planning logic, while C/Z materials follow another.
These rules are then applied consistently across all materials in that category. The defined service levels are used in both simulation and MRP matching, so calculated safety stock values and replenishment behavior follow the planning strategy you’ve set. This reduces manual master data maintenance and ensures proper inventory alignment with demand.
-
Stabilize Replenishment and Coverage Logic

Replenishment Lead Time (RLT) is calculated using defined priority logic and compared to forward-looking Range of Coverage (RoC). This makes it possible to identify materials where coverage is too short relative to replenishment time, or excessively long relative to demand. Inventory availability is evaluated using days of supply versus actual lead time performance — not stock quantity alone.
For example, if a material has 10-20 days of supply but requires 51-60 days to replenish based on the RLT, then it is immediately flagged as a supply risk (red section). Materials are positioned within a structured RoC matrix, allowing planners to identify exposure at a glance and drill into detailed analysis directly within SAP.
-
Simulate Inventory and Service-Level Adjustments

Planners can simulate changes to safety stock levels, service targets, lot sizes, and reorder logic without immediately updating SAP master data. The impact on coverage, stock value, and MRP proposals can be reviewed before parameters are transferred. This allows adjustments to be tested and validated before they affect live planning runs.
-
Match and Apply Corrected Parameters to SAP Master Data (MRP Matching)
GIB compares recalculated MRP parameters — including safety stock, lot-sizing procedures, MRP types, and service levels — against existing SAP material master data. Differences between current and proposed values are clearly identified, allowing planners to review and approve adjustments before they are written back. Updates follow a controlled process aligned with defined policy rules, ensuring parameter changes are deliberate and consistent across materials.
"By using GIB Inventory and GIB Operations, we have sped up our material planning processes by more than 67%. We have been able to reduce our scrapping by 73% - the interaction with GIB Forecast has played a significant role here - and last but not least, we have been able to increase our delivery readiness by 3%.

Part of the GIB Platform
Designed to increase the operational effectiveness of your SAP system, GIB delivers a unique set of solution applications purpose-built for supply chain performance. Embedded directly within SAP ECC and SAP S/4HANA, the GIB platform introduces built-in cross-functional intelligence, connecting data and decisions across demand, inventory, MRP, procurement, and production.

Why Our Customers Love GIB Inventory
We urgently needed a solution that would provide us with the necessary stock transparency by first identifying slow movers and determining dead stocks, second performing ABC/XYZ analysis quickly and reliably – until now we had been using Microsoft Excel for this – and third, reliably checking the level of safety stocks and reorder points. [...] GIB makes it easy to meet our customers' requirements as precisely as possible and at the same time always be at the cutting edge of technology.

Thanks to company-wide visibility, the GIB Inventory module now supports inventory-optimized purchasing decisions and has significantly improved our delivery reliability.
Udo Wessbecher
Head of IT, Supply Chain Management | ZF
The deciding factor for our choice of GIB Operations and GIB Inventory modules were, on one hand, the comparison that made it glaringly obvious to us how much we needed such a solution, and on the other hand, the consistent data transparency that this add-on ensures.
