Here is a brief description of the key tables in Oracle Inventory.
| Table | Description |
| MTL_PARAMETERS | It maintains a set of default options like general ledger accounts; locator, lot, and serial controls, inter-organization options, costing method, etc. for each organization defined in Oracle Inventory. Each organization’s item master organization (MASTER_ORGANIZATION_ID) and costing organization (COST_ORGANIZATION_ID) are maintained here. |
| MTL_SYSTEM_ITEMS_B | This is the definition table for items. This table holds the definitions for inventory items, engineering items, and purchasing items. The primary key for an item is the INVENTORY_ITEM_ID and ORGANIZATION_ID. Therefore, the same item can be defined in more than one organization. Items now support multilingual description. MLS is implemented with a pair of tables: MTL_SYSTEM_ITEMS_B and MTL_SYSTEM_ITEMS_TL. Translations table (MTL_SYSTEM_ITEMS_TL) holds item Description and Long Description in multiple languages. |
