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 ).
