Locking a QueueLocate this document in the navigation structure

Use

This example shows how you can lock, retroactively or in advance, the processing of qRFC units of type q that use a specific queue.

Prerequisites

In this example, we use the outbound procedure.

Procedure

In the 'QUEUE_TOP' queue, the next unit to be processed is locked. In the 'QUEUE_BOTTOM' queue, the next unit to be written to this queue is locked.

Example

DATA: my_destination TYPE REF TO if_bgrfc_destination_outbound,

dest_name TYPE bgrfc_dest_name_outbound,

queue_name TYPE qrfc_queue_name.

dest_name = 'MY_DEST'.

queue_name = 'QUEUE_TOP'.

cl_qrfc_lock_outbound=>lock_queue_from_top(

queue_name = queue_name

dest_name = dest_name

ignore_duplicates = abap_true )

queue_name = 'QUEUE_BOTTOM'.

cl_qrfc_lock_outbound=>lock_queue_from_current_pos(

queue_name = queue_name

dest_name = dest_name

ignore_duplicates = abap_true ).
