Synchronous RFC

[Former Member]

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

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 .
