1、事务处理可处理量
RCV_RECEIPTS_QUERY_SV.POST_QUERY
2、RCV: Processing Modes
- On-line
联机处理，保存立即处理，界面上不能做其他操作 - Immediate
立即，保存后自动运行“接收事务处理处理器”（RVCTP）PROCESSING_MODE=IMMEDIATE，用户可以做其他操作。 - Batch
批量，保存后不会自动提交请求，当手动运行“接收事务处理处理器”（RVCTP）PROCESSING_MODE=BATCH时才会处理。

When receiving transactions are performed, data is written to the RCV_TRANSACTIONS_INTERFACE table (Status=PENDING) for subsequent processing based on the value of Profile RCV: Processing Mode (ON-LINE, IMMEDIATE or BATCH). Although this profile is typically set at the System Level, Users may change this value via Personal Profiles.
Processing Mode values:
On-line:
This is the most commonly used processing mode. When the user saves a transaction, no other application activity can be performed until the process completes. Either the number of records saved will be indicated for a successful transaction or an error message will be displayed. Uses Receiving Transaction Manager (executable RCVOLTM, located in $PO_TOP/bin).
Immediate:
When the user saves a transaction, the Receiving Transaction Processor concurrent program will automatically start and process the data in the RCV_TRANSACTIONS_INTERFACE table that was created for the Receipt. Control of the form is returned to the User who may then perform other application activity. Transaction errors that occur are written to the PO_INTERFACE_ERRORS table and can be viewed from the Transaction Status Summary. Additional information may be available in the log file for the Receiving Transaction Processor concurrent request (View/Requests). Uses Receiving Transaction Processor (executable RVCTP, located in $PO_TOP/bin).
Batch:
When the user saves a transaction, the data remains in the RCV_TRANSACTIONS_INTERFACE table until the Receiving Transaction Processor concurrent program is run via report submission. Control of the form is returned to the User who may then perform other application activity. When the Receiving Transaction Processor runs, it will process all PENDING records for PROCESSING_MODE=BATCH. Transaction errors that occur are written to the PO_INTERFACE_ERRORS table and can be viewed from the Transaction Status Summary Form.
