able	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.
MTL_ITEM_STATUS	This is the definition table for material status codes. Status code is a required item attribute. It indicates the status of an item, i.e., Active, Pending, Obsolete.
MTL_UNITS_OF_MEASURE_TL	This is the definition table for both the 25-character and the 3-character units of measure. The base_uom_flag indicates if the unit of measure is the primary unit of measure for the uom_class. Oracle Inventory uses this table to keep track of the units of measure used to transact an item.
MTL_ITEM_LOCATIONS	This is the definition table for stock locators. The associated attributes describe which subinventory this locator belongs to, what the locator physical capacity is, etc.
MTL_ITEM_CATEGORIES	This table stores inventory item assignments to categories within a category set. For each category assignment, this table stores the item, the category set, and the category. Items always may be assigned to multiple category sets. However, depending on the Multiple Assignments Allowed attribute value in a given category set definition, an item can be assigned to either many or only one category in that category set.
MTL_CATEGORIES_B	This is the code combinations table for item categories. Items are grouped into categories within the context of a category set to provide flexible grouping schemes. Item categories now support multilingual category description. MLS is implemented with a pair of tables: MTL_CATEGORIES_B and MTL_CATEGORIES_TL. MTL_CATEGORIES_TL table holds translated Description for Categories.
MTL_CATEGORY_SETS_B	It contains the entity definition for category sets. A category set is a categorization scheme for a group of items. Items may be assigned to different categories in different category sets to represent the different groupings of items used for different purposes. An item may be assigned to only one category within a category set, however. STRUCTURE_ID identifies the flexfield structure associated with the category set. Category Sets now support multilingual category set name and description. MLS is implemented with a pair of tables: MTL_CATEGORY_SETS_B and MTL_CATEGORY_SETS_TL. MTL_CATEGORY_SETS_TL table holds translated Name and Description for Category Sets.
MTL_DEMAND	This table stores demand and reservation information used in Available To Promise, Planning and other Manufacturing functions. There are three major row types stored in the table: Summary Demand rows, Open Demand Rows, and Reservation Rows.
MTL_SECONDARY_INVENTORIES	This is the definition table for the subinventory. A subinventory is a section of inventory, i.e., raw material, finished goods, etc. Subinventories are assigned to items (in a many to one relationship), indicating a list of valid places where this item will physically exist in inventory.
MTL_ONHAND_QUANTITIES	It stores quantity on hand information by control level and location. It is maintained as a stack of receipt records, which are consumed by issue transactions in FIFO order. The quantity on hand of an item at any particular control level and location can be found by summing TRANSACTION_QUANTITY for all records that match the criteria.
MTL_TRANSACTION_TYPES	It contains seeded transaction types and the user defined ones. USER_DEFINED_FLAG will distinguish the two. The table also stores the TRANSACTION_ACTION_ID and TRANSACTION_SOURCE_TYPE_ID that is associated with each transaction type.
MTL_MATERIAL_TRANSACTIONS	This table stores a record of every material transaction or cost update performed in Inventory. Records are inserted into this table either through the transaction processor or by the standard cost update program. The columns TRANSACTION_TYPE_ID, TRANSACTION_ACTION_ID, TRANSACTION_SOURCE_TYPE_ID, TRANSACTION_SOURCE_ID and TRANSACTION_SOURCE_NAME describe what the transaction is and against what entity it was performed.
MTL_ITEM_ATTRIBUTES	This table stores information on item attributes. Each row in the table corresponds to an attribute. The table stores the attribute name, the corresponding user-friendly name seen by the users, and the kind of validation enforced on the attribute.
MTL_ITEM_CATALOG_GROUPS_B	This is the code combinations table for item catalog groups. An item catalog group consists of items that can be described by the same set of descriptive elements or item properties. When an item is associated with an item catalog group, the item inherits the descriptive elements for that group which then behave like additional item attributes.
MTL_ITEM_REVISIONS_B	It stores revision levels for an inventory item. When an item is defined a starting revision record is written out to this table, so every item will at least have one starting revision.
MTL_ITEM_TEMPLATES_B	This is the definition table for item templates. It contains the user-defined name (TEMPLATE_NAME) and description (DESCRIPTION) ONLY for backward compatibility. You can use a template to set certain item attributes.
MTL_DESCRIPTIVE_ELEMENTS	It stores the descriptive element definitions for an item catalog group. Descriptive elements are defining properties used to describe in the catalog group.
MTL_DESCR_ELEMENT_VALUES	It stores the descriptive element values for a specific item. When an item is associated with a particular item catalog group, one row per descriptive element (for that catalog group) is inserted into this table.
ORG_ACCT_PERIODS	It holds the open and closed financial periods for organizations.
MTL_CUSTOMER_ITEMS	It stores customer item information for a specific customer. Each record can be defined at one of the following levels: Customer, Address Category, and Address. The customer item definition is organization independent.
MTL_SYSTEM_ITEMS_INTERFACE	It temporarily stores the definitions for inventory items, engineering items and purchasing items before loading this information into Oracle Inventory.
MTL_TRANSACTIONS_INTERFACE	It allows calling applications to post material transactions (movements, issues, receipts etc. to Oracle Inventory  transaction module.
MTL_ITEM_REVISIONS_INTERFACE	It temporarily stores revision levels for an inventory item before loading this information into Oracle Inventory.
MTL_ITEM_CATEGORIES_INTERFACE	This table temporarily stores data about inventory item assignments to category sets and categories before loading this information into Oracle Inventory.
MTL_DESC_ELEM_VAL_INTERFACE	This table temporarily stores descriptive element values for an item that is associated with an item catalog group before loading this information into Oracle Inventory.
MTL_DEMAND_INTERFACE	It is the interface point between non-Inventory applications and the Inventory demand module. Records inserted into this table are processed by the Demand Manager concurrent program.
MTL_INTERFACE_ERRORS	It stores errors that occur during the item interface process reporting where the errors occurred along with the error messages.

GL Tables

General Ledger tables can be grossly classified into following 5 categories. Here are few important tables in each category.

Ledgers Tables:

GL_LEDGERS: Stores information about the ledgers defined in the Accounting Setup Manager and the ledger sets defined in the Ledger Set form. Each row includes the ledger or ledger set name, short name, description, ledger currency, calendar, period type, chart of accounts, and other information.
GL_CODE_COMBINATIONS: Stores valid account combinations for each Accounting Flexfield structure within your Oracle General Ledger application.

Period Tables:

GL_PERIODS: Stores information about the accounting periods you define using the Accounting Calendar form.
GL_PERIOD_SETS: Stores the calendars you define using the Accounting Calendar form.
GL_PERIOD_TYPES: Stores the period types you define using the Period Types form. Each row includes the period type name, the number of periods per fiscal year, and other information.

Journal Tables:

GL_JE_BATCHES: Stores journal entry batches. Each row includes the batch name, description, status, running total debits and credits, and other information.
GL_JE_HEADERS: Stores journal entries. There is a one-to-many relationship between journal entry batches and journal entries. Each row in this table includes the associated batch ID, the journal entry name and description, and other information about the journal entry.
GL_JE_LINES: Stores the journal entry lines that you enter in the Enter Journals form. There is a one-to-many relationship between journal entries and journal entry lines. Each row in this table stores the associated journal entry header ID, the line number, the associated code combination ID, and the debits or credits associated with the journal line.
GL_JE_SOURCES: Stores journal entry source names and descriptions. Each journal entry in your Oracle General Ledger application is assigned a source name to indicate how it was created. This table corresponds to the Journal Sources form.
GL_JE_CATEGORIES: Stores journal entry categories. Each row includes the category name and description.

Conversion and consolidation tables:

GL_CONSOLIDATION: Stores information about your consolidation mappings. Each row includes a mapping’s ID, name, description, and other information. This table corresponds to the first window of the Consolidation Mappings form. You need one row for each consolidation mapping you define.
GL_CONSOLIDATION_ACCOUNTS: Stores the account ranges that you enter when you consolidate balances using the Transfer Consolidation Data form. This table corresponds to the Account Ranges window of the Transfer Consolidation Data form.
GL_DAILY_RATES: Stores the daily conversion rates for foreign currency transactions. It replaces the GL_DAILY_CONVERSION_RATES table. It stores the rate to use when converting between two currencies for a given conversion date and conversion type.
GL_DAILY_BALANCES: Stores daily aggregate balances for detail and summary balance sheet accounts in sets of books with average balances enabled.

Budgeting tables:

GL_BUDGET_TYPES: Stores information about budget types. Oracle General Ledger supports only one budget type, ‘STANDARD’. Therefore, this table always contains only one row.
GL_BUDGET_ASSIGNMENTS: Stores the accounts that are assigned to each budget organization. Each row includes the currency assigned to the account and the entry code for the account. The entry code is either ‘E’ for entered or ‘C’ for calculated. This table corresponds to the Account Assignments window of the Define Budget Organization form.
GL_BUDGET_INTERIM: It is used internally by Oracle General Ledger applications to post budget balances to the GL_BALANCES table. Rows are added to this table whenever you run the budget posting program. The budget posting program updates the appropriate budget balances in GL_BALANCES based on the rows in this table, and then deletes the rows in this table that it used.

Interface Tables:

GL_INTERFACE: It is used to import journal entry batches through Journal Import. You insert rows in this table and then use the Import Journals window to create journal batches.
GL_INTERFACE_CONTROL: It is used to control Journal Import execution. Whenever you start Journal Import from the Import Journals form, a row is inserted into this table for each source and group id that you specified. When Journal Import completes, it deletes these rows from the table.
GL_BUDGET_INTERFACE: It is used to upload budget data into your Oracle General Ledger application from a spreadsheet program or other external source. Each row includes one fiscal year’s worth of budget amounts for an account.
