Error maximum size of requests for one LUW

Question

Hi all,
My problem is:
In SAP ERP i call a function (ZQTC_NFE_CANCEL_XML_PI) that is implemented in SAP PI.
Follow below my source code of a call:
start----
DATA: gv_rfcdest TYPE rfcdest,
      gs_cancel_xml TYPE zqtc_cancel_xml_layout.
gv_rfcdest = 'SAPAVGXI'
CALL FUNCTION 'ZQTC_NFE_CANCEL_XML_PI' IN BACKGROUND TASK
   DESTINATION gv_rfcdest
   EXPORTING
     i_cancel_xml          = gs_cancel_xml
   EXCEPTIONS
     communication_failure = 1
     system_failure        = 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.
COMMIT WORK.
end----
When execute this function the error is "maximum size of requests for one LUW"
Attention
gs_cancel_xml is not big.
Can anyone help me please!

Hello,
RFC destination progid created in R/3 should be same in XI system either D or Q system
In your case check the RFC destination used and progid associated in that and make sure that the same progId exists in the system you want to receive data
Note : progID is key for receiving data so make sure only one is active at a time.(in your case required D or Q s id in other system change the progid)
