Hello all,

just a (late) follow-up: SAP_WAPI_CREATE_EVENT_EXTENDED works, I’ve just had to work around two issues:

I needed to pass event parameters that contain a table. This is not possible using the parameter INPUT_CONTAINER, you have to prepare an IFS_XML_CONTAINER XSTRING. Is it common knowledge how to do this or something  worth blogging about? ☺

The second issue – which I still do not understand – is a problem with the RFC call:
This works:
  CALL FUNCTION 'SAP_WAPI_CREATE_EVENT_EXTENDED' DESTINATION l_rfcdest
    EXPORTING
      catid           = ls_lpor-catid
      typeid          = ls_lpor-typeid
      instid          = ls_lpor-instid
      event           = `MY_EVENT` " STRING!
    TABLES
      input_container = lt_container.
This does NOT work:
  CALL FUNCTION 'SAP_WAPI_CREATE_EVENT_EXTENDED' DESTINATION l_rfcdest
    EXPORTING
      catid           = ls_lpor-catid
      typeid          = ls_lpor-typeid
      instid          = ls_lpor-instid
      event           = 'MY_EVENT' " C
    TABLES
      input_container = lt_container.
Note the difference of backticks for a string literal (``) versus ‘common’ character. If you use a C literal, only the first character of the event name is transferred.

Best regards
  Volker

Good to hear I've been of some help :)

If your 'remote' Wf Errors then just like any other Wf in Error, it will appear in the remote system in SWPR and Wf Admin should be monitoring this.  If your calling Wf is using 'dynamic parallel processing' then you could build something into this to deadline each leg (each leg I suggest could be the remote system id/Object Key), then each leg could have it's own deadlining .... and I imagine now you could get creative and imagine allsorts of things to do, but probably best to keep it simple.

Good luck, sounds like an interesting piece of work.

Andy,

Thanks for that hint, I’ll give this a try. The only thing I’m concerned about is what will happen if the sub-workflow aborts with some obscure error and no event will be transmitted back, but I think I can handle this. I will need to start the sub-workflow in multiple systems and await all of the results, which sounds like a use case for the table driven dynamic parallel processing described in the PW book. I’m unsure on how to match the request and response events, but that may simply be a case of “haven’t tried it yet”…

Best regards
  Volker Wegert

I am doing something like this between SRM and ECC.  I found that the SAP_WAPI_CREATE_EVENT & SAP_WAPI_CREATE_EVENT_EXTENDED FM's are RFC enabled, so my SRM Wf has a task to call SAP_WAPI_CREATE_EVENT_EXTENDED in ECC to raise an Event in ECC and start a Wf there.  The next step in my SRM flow is a Wait for an Event which is triggered in a similar manner from ECC, and the SRM process continues

Hello,

I’m trying to configure a set of ABAP systems so that I can let a “master workflow” in one system start a “sub-workflow” in another system and wait for its completion. As far as I can see, http://help.sap.com/saphelp_470/helpdata/en/9b/9f9138d380f50fe10000009b38f8cf/content.htm (section “Sending a Wf-XML document to another SAP system and starting a workflow with feedback”) is the function I’m looking for. I’m trying to follow the steps outlined in http://help.sap.com/saphelp_470/helpdata/EN/cc/9f9138d380f50fe10000009b38f8cf/content.htm to configure the web server, and I’m unsure about two issues:

•         Is there a pre-defined role or profile that can be assigned to the service user? If not, is there a recommendation about the permissions required for the service user? Somehow I don’t think that opening an anonymous service with SAP_ALL is a good idea…

•         Since both user/password and client have to be entered in the service data – am I correct in assuming that if I need to connect to multiple clients in one system, I will have to create several copies of the SICF service that each point to a different client?

Thanks a lot
  Volker

Hi Volker,
Just querying whether you wouldn’t rather try that in SAP NetWeaver BPM? Sounds like a better fit.
Rgds,
Jocelyn
