Items and Item Organization
Items and Item Organization
This domain tests item master data and how items become transactable in an inventory organization. The exam focuses on the master organization, item attributes, organization assignment, and controls such as lot, serial, and status.
Core rules
- Items are defined once in the item master organization, then assigned to inventory organizations. The master organization holds the item definition; the assigned organization holds org-specific attributes.
- Item attributes include unit of measure, lot control, serial control, shelf life, negative inventory, and cost profile. Some are controlled at master level and some at organization level.
- Item templates speed creation by pre-populating attribute groups. Categories and catalogs support search and reporting but do not replace organization assignment.
- Item status can block transactions. A status of Active permits transactions; Inactive or restricted statuses prevent them.
Worked example
You create item FIN-100 in the master organization with UOM Each, lot control No, serial control No. You assign it to WH1 and WH2. In WH1 you set the cost profile to Average; in WH2 you leave the default. The item can now be received in both organizations. If you later change the primary UOM from Each to Box, existing on-hand quantities are not automatically converted; you must plan a UOM conversion and may need a new item. The reasoning: the master definition is shared, but organization assignment and org-level attributes determine where and how the item transacts.
Traps
- Creating an item only in the master organization and expecting it to transact in a warehouse.
- Changing lot or serial control after transactions exist; this can break existing balances and genealogy.
- Confusing item categories with item organizations; categories are classification, not inventory structure.
- Overlooking item status when a transaction fails with no obvious quantity issue.
