The below post shows how to club multiple QUEUE ( one queue having multiple FM calls) into a single LUW. After calling the TWO queues with their respective FMs , at the end Commit work happens so every thing is put into a single LUW. Execute the program.
REPORT zoutqueue_inqueue.
DATA ls TYPE scarr.
*** first queue *****
CALL FUNCTION ‘TRFC_SET_QIN_PROPERTIES’
EXPORTING
qout_name = ‘OUT_QUEUE1’
qin_name = ‘INN_QUEUE1’.
clear ls.
ls-carrid = ‘XX’.
CALL FUNCTION ‘ZCREATE_FLIGHT_REC’
IN BACKGROUND TASK
“AS SEPARATE UNIT ” creates a separate luw
DESTINATION ‘SRC_TO_TGT’
EXPORTING
is = ls.
CALL FUNCTION ‘TRFC_SET_QIN_PROPERTIES’
EXPORTING
qout_name = ‘OUT_QUEUE1’
qin_name = ‘INN_QUEUE1’.
CLEAR ls.

ls-carrname = ‘XX AIRLINE’.
CALL FUNCTION ‘ZUPDATE_FLIGHT_REC’
IN BACKGROUND TASK
“AS SEPARATE UNIT ” creates a separate luw
DESTINATION ‘SRC_TO_TGT’

*** Second queue ***
CALL FUNCTION ‘TRFC_SET_QIN_PROPERTIES’
EXPORTING

COMMIT WORK.
WRITE 
‘Check outbound queue in source system in Tx- SMQS’.
WRITE ‘Check Inbound queue in target system in Tx- SMQR’.
Step1. Source System: Tx- SMQR( out bound scheduler). Select the line and click on the qRFC Monitor button.
Step2. Source System: Select both the out bound queues and double click on it.
Step3. Source System: Double click on it.
Step4. Source System: So here we have a single TID for all the FM calls that belongs to two different Queues. process the out bound queue.
Step5. Target System: Tx- SMQS( Inbound Scheduler): Select the line and click on the qRFC monitor button.
Step6. Target System: Select both the inbound queues. Double click on it.
Step7. Target System: Double click on the queue name.
Step8. Target System:: So here we have a single technical ID for all the FM calls that belongs to two different queues.
See the next post how each queue FM calls are assigned to separated LUWs
