How To Call SAP Transaction Remotely

In this tutorial, you will learn how to call a transaction remotely using function module ‘ABAP4_CALL_TRANSACTION’, what I mean by remotely is that you can call it from an external system that can be SAP or non SAP. But make sure that you have the proper authority in the calling system.
This ABAP code below will demonstrate you how to call transaction code QA01to create an inspection plan data.
Data: itab_bdc like BDCDATA occurs 0 with header line,
itab_SPAGPA like RFC_SPAGPA occurs 0 with header line ,
itab_messTab like BDCMSGCOLL occurs 0 with header line.
Data: d_sysubrc like sy-subrc.

CALL FUNCTION ‘ABAP4_CALL_TRANSACTION’
EXPORTING
TCODE = ‘QA01′
SKIP_SCREEN = ‘ ‘
MODE_VAL = ‘A’
UPDATE_VAL = ‘A’
IMPORTING
SUBRC = d_sysubrc
TABLES
USING_TAB = itab_bdc
SPAGPA_TAB = itab_SPAGPA
MESS_TAB = itab_messTab
EXCEPTIONS
CALL_TRANSACTION_DENIED = 1
TCODE_INVALID = 2
OTHERS = 3
.
IF SY-SUBRC <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
* WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
When you execute the program, you will see that it opened the Transaction QA01 just like the picture below.
