Redesign warehouse and site semantics rather than copying them, choose tracking dimension groups that match real granularity, settle the costing method before the variance crosswalk, and treat advanced warehouse management as a decision to be earned.
The Product module built the catalogue. This module decides where stock lives, how finely it is tracked, what it is worth, and how much of that survives cutover.
The target has three levels where the source effectively has two, and the extra level is the one that carries the accounting.
The target expresses inventory granularity through dimension groups attached to the product: a storage dimension group covering site, warehouse and location, and a tracking dimension group covering batch and serial.
Valuation in the target is a property of the item model group, which governs the valuation method, whether the item is physically or financially updated, whether negative inventory is permitted, and how the inventory close settles issues against receipts. Standard cost brings a costing version carrying the cost records themselves.
The target offers two warehousing models: basic warehousing, which manages stock by warehouse and location, and advanced warehouse management, which adds work templates, location directives, licence plates, wave processing and mobile-device-directed work.
On-hand balances. Quantity and cost, at the finest tracked granularity: site, warehouse, location, batch and serial. Both halves matter — a quantity-only load produces correct stock and wrong inventory value, and the value error lands in the opening balance reconciliation where it is expensive to unpick.
The validation set for this path names inventory by site, location, lot and serial where used. Reconcile at that granularity, and add the value dimension:
The distribution depth of any given tenant is exactly the kind of edition- and module-sensitive fact the gap register warns about: do not assume every tenant uses advanced distribution even if it is licensed. Prove real process use before designing to it.
The target splits what the source combines: an operational site carrying context and a warehouse carrying stock, with locations underneath. Branch and site must not collapse onto the same object without evidence, because the resulting loss of either the accounting boundary or the ownership model only appears once cross-entity movement…
