"asynchronous method call"

ChristianFi — Thu, 27 Jan 2005 20:08:15 GMT

Dear all,

I am writing a program for which I would like to enable parallel processing. As the programm is designed in classes and methods, I thought it would be nice and consistent to use methods calls instead of asynchronous function calls. I found a class for remote method calls but this does not appear asynchronous.

Any idea if it is possible?

Thanks

Christian

Chris,

You can do parallel processing by calling a function module.

Program A

Call function module B starting new task 'NEWTASK'

exporting

param1 = param1

exceptions

communication_failure = 1

system_failure = 2.

Yes I know,

but the question was if there is something similar for method calls. (the reason why I ask is that I do not want to encapsulate the development in fm (which would be neceassary (or perform some weird call back scenario).

Thanks for the input anyway.

Hi,

Perhaps a way to accomplish this is to create an OO transaction in SE93. Take a look at http://help.sap.com/saphelp_nw04/helpdata/en/a8/485d60cf4611d4b2e90050dadfb92b/frameset.htm for further details.

You can then issue the statement CALL TRANSACTION <tcode> UPDATE 'A' (for asynchronous), or as suggested in one of previous discussions, use


CALL FUNCTION 'ABAP4_CALL_TRANSACTION' STARTING NEW TASK 'TEST' 
  DESTINATION 'NONE' 
  EXPORTING 
      TCODE = <your_oo_tcode> 
  EXCEPTIONS 
    COMMUNICATION_FAILURE = 1 MESSAGE MSG_TEXT 
    SYSTEM_FAILURE        = 2 MESSAGE MSG_TEXT.

You can also look at ABAP Object Services, especially Transaction Service, at http://help.sap.com/saphelp_nw04/helpdata/en/ab/9d0a3ad259cd58e10000000a11402f/frameset.htm.

Hope this helps.
