Calling a BAPI in R3 from CRM

Question

I called a BAPI to retrieve information in R3. However, I encountered a problem when our R3 is in the downtime period. It raises a short dump for my program. Is there any exception that I can catch to prevent or other solutions to prevent this short dump.

Answer 1

Hi again,
1.  I use the exception like the below code, right?
Yes, use it like this only.
2.
Does my RFC function on R3 have these exceptions ?
No, the RFC/BAPI does not have
any such exceptions
in the definition
(u will see in SE37, that,
the EXCEPTIONS tab is empty)
3. BUT
  IT IS A FACILITY (AUTOMATIC FACILITY)
  PROVIDED BY R3
  TO DETECT SUCH COMMUNICATION PROBLEMS
(The RFC FM/BAPI does not Take care of this by itself,
bcos, if communication is not there,
then the FM is not at all called in the target system)
4.
If not, how can the system know that when the system is cracked, it will raise the exception 2?
Do not worry.
If the target server is DOWN,
then your program will not give run time error.
However, u should chec sy-subrc
to DETECT, some error has occured bcos
of communication.
5. To get a taste of it,
  just copy paste
(Change the DESTINATION as per your requriement,
  give some wrong destination,
  give some right one
  etc)
6.
REPORT abc.
DATA: msg_text(80) TYPE c.
CALL FUNCTION 'RFC_PING' DESTINATION 'PRD'
EXCEPTIONS
communication_failure = 1 MESSAGE msg_text
system_failure = 2 MESSAGE msg_text.
IF sy-subrc <> 0.
*----- MESSAGE
message 'problem' type 'I'.
ENDIF.
