Synchronous RFC

Former Member — Thu, 18 May 2006 12:15:48 GMT

Hi,

I am making a synchronous RFC call passing a structure and expecting a return value like "No of records updated"

I am passing a structure to XI from R/3 using RFC call. Xi has to insert this structure in a legacy database table and return the number of records inserted.

It is working fine when everything is fine but when the legacy database is down it is giving me a short dump

"call to messaging system failed: com.sap.aii.af.ra.ms.api.DeliveryException:" How to handle this exception? Please send me some solution to this ASAP.

My code is given below

CALL FUNCTION 'RFC_SYSTEM_INFO' DESTINATION l_rfcdest

IMPORTING

rfcsi_export = l_rfcsi

rfc_login_complete =
dialog_user_type =
current_resources =
maximal_resources =
recommended_delay =

EXCEPTIONS

communication_failure = 1 MESSAGE l_msg

system_failure = 2 MESSAGE l_msg

OTHERS = 3.

IF sy-subrc EQ 0.

IF l_msg IS INITIAL.

CALL FUNCTION 'Z_SAP_TO_CADB' DESTINATION l_rfcdest

TABLES

pt_items = pt_items

CHANGING

return = return1.

Here i am checking for the RFC destination first, if RFC destination is fine then only i am making an RFC call to XI.

Pt_items is the structure i am passing to XI

return1 is where i am expecting the number of records inserted.

Thanks in advance

Rajesh.

Try adding the exception handling to the Z_SAP_TO_CADB function call. So the following should be your call:

CALL FUNCTION 'Z_SAP_TO_CADB' DESTINATION l_rfcdest

TABLES

pt_items = pt_items

CHANGING

return = return1

EXCEPTIONS

communication_failure = 1 MESSAGE l_msg

system_failure = 2 MESSAGE l_msg

OTHERS = 3.

If sy-subrc eq 0.

Your Logic.

else.

Exception handling.

endif.

Hope it helps.

Hi ,

Try using the below FM to check the destination and if its successful then cal FM 'Z_SAP_TO_CADB' .

Check RFC Destination++

CALL FUNCTION 'RFC_VERIFY_DESTINATION'

EXPORTING

destination = ws_dest

AUTOUPDATE = ' '
TIMEOUT = 60
IMPORTING
RFCSI_EXPORT =
RFC_LOGIN_COMPLETE =
DIALOG_USER_TYPE =
CURRENT_RESOURCES =
MAXIMAL_RESOURCES =
RECOMMENDED_DELAY =
CHARSIZE =
UPDATED =

EXCEPTIONS

internal_failure = 1

timeout = 2

dest_communication_failure = 3

dest_system_failure = 4

update_failure = 5

no_update_authority = 6

OTHERS = 7.

Sreejesh .
