Interface Program:

Launch the Transaction Manager through Interface Manager or explicitly call the API – INV_TXN_MANAGER_PUB.PROCESS_TRANSACTIONS () to launch a dedicated transaction worker to process them.

The Transaction Manager picks up the rows to process based on the LOCK_FLAG, TRANSACTION_MODE, and PROCESS_FLAG. Only records with TRANSACTION_MODE of 3, LOCK_FLAG of ’2′, and PROCESS_FLAG of ’1′ will be picked up by the Transaction Manager and assigned to a Transaction Worker. If a record fails to process completely, then PROCESS_FLAG will be set to ’3′ and ERROR_CODE and ERROR_EXPLANATION will be populated with the cause for the error.

Base Tables:

MTL_ON_HAND_QUANTITIES
MTL_LOT_NUMBERS
MTL_SERIAL_NUMBERS

Validations:

Validate organization_id
Check if item is assigned to organization
Validate disposition_id
Check if the item for the org is lot controlled before inserting into the Lots interface table.
Check if the item for the org is serial controlled before inserting into Serial interface table.
Check if inventory already exists for that item in that org and for a lot.
Validate organization_id, organization_code.
Validate inventory item id.
Transaction period must be open.

Interface tables:

MTL_TRANSACTIONS_INTERFACE
MTL_MTL_TRANSACTION_LOTS_INTERFACE (If the item is Lot controlled)
MTL_SERIAL_NUMBERS_INTERFACE (If the item is Serial controlled)

MTL_TRANSACTIONS_INTERFACE:

TRANSACTION_SOURCE_NAME (ANY USER DEFINED VALUE),
TRANSACTION_HEADER_ID (MTL_MATERIAL_TRANSACTIONS_S.NEXTVAL)
TRANSACTION_INTERFACE_ID (MTL_MATERIAL_TRANSACTIONS_S.NEXTVAL – If item is lot or serial controlled, use this field to link to mtl_transactions_interface otherwise leave it as NULL),
TRANSACTION_DATE,
TRANSACTION_TYPE_ID,
PROCESS_FLAG (1 = Yet to be processed, 2 = Processed, 3= Error)
TRANSACTION_MODE (2 = Concurrent – to launch a dedicated transaction worker to explicitly process a set of transactions. 3 = Background – will be picked up by transaction manager polling process and assigned to transaction worker. These will not be picked up until the transaction manager is running)
SOURCE_CODE,
SOURCE_HEADER_ID,
SOURCE_LINE_ID (Details about the source like Order Entry etc for tracking purposes)

MTL_TRANSACTION_LOTS_INTERFACE:
