Translate the EBS stock model — inventory organization, subinventory, locator, receiving and costing — as one connected design rather than four table mappings, and build the valuation reconciliation that the transition plan will demand.
Inventory is where the organisational design, the product design and the posting design meet, and it is where a programme discovers whether those three were built consistently.
The standard mapping — inventory organization to site, subinventory to warehouse, locator to location — is right often enough to be dangerous. It is right for physical storage. It is wrong for everything else a subinventory can be made to mean.
The gap register rates locator-heavy and warehouse-management-customised subinventory models as a medium-impact data-model gap, with a note that says plainly what the risk is: basic site and warehouse mapping is straightforward; deep locator and warehouse-management behaviour often is not.
EBS permits costing behaviour to vary by inventory organisation. The target resolves valuation through the item model group attached to the released product within a legal entity, with costing versions carrying standard cost records where the standard model is used.
The purchase order receipt accrual rule carries the instruction to model perpetual versus period-end accrual explicitly, and it belongs in this module as much as in the Posting Engine module because the receiving stage is where physical and accounting positions diverge.
The inter-organisation transfer rule asks a question rather than answering it: do historical organisation transfers become intra-entity transfers or true intercompany?
The playbook's accounting control for this module is inventory valuation by organisation and site, and the transition plan's gate for the inventory wave is that inventory value agrees with the inventory control account to the agreed tolerance.
Inventory translation is a single connected design across the stock hierarchy, receiving and costing, and the source guidance warns that mapping those pieces in isolation creates reconciliation problems.
