AW: Triggering workflow from BSP

Wed Jun 1 18:14:18 EDT 2005

Thanks Nate for your inputs.

I agree with you, But here our process is not relavant SAP functionality. They are completely custom process. SAP's BSP & WebFlow are being used as platforms to impliment as the client is looking for web-based interface for the existing request-approval process. No details about the "Request" are being saved with in SAP, SAP just provides BSP page to submit the request and triggers workflow. And workflow container holds the data[request & approve data] till the end of workflow/process. 

Hence no custom business objects( or tables) being created, there by no events associated with.

Yes, no hardcoding of Agents. They are being determined from Org. Structure or from Cusotm table.

I could trigger workflow with 'SAP_WAPI_START_WORKFLOW'.

Pramod

Hi Pramod

I did this once for an invoice approval workflow.  The approval took place in a web-based java application which connected to SAP via RFC:  I tried to avoid as much as possible embedding the workflow logic in the external (for you BSP) application,  that meant coupling the BSP page loosely to the workflow engine using as much as possible the raising of Business Object Events.  

- could you start your workflow with the raising of an event instead of 'SAP_WAPI_START_WORKFLOW'?
- could you use a SAP rule for finding the agents instead of  hard-coding them in the container?

The danger is  there that you end up reprogramming a lot of functionality that the workflow-engine already does.  We ended up starting a full fledged SAP workflow in the background (no body actually used the SAP inbox) that was just event-triggered via the web-based screens, data was updated via  BAPIs and the workflow via SAP_WAPIs.  

Just a few points you might consider which would make the design of your workflow more flexible.

Yours truly
Nate

Hi Pramod,

Here is some input for your questions.

1. I have triggered without any business objects. Container can be
filled as below and call the workflow using the following sample code.
C_WF_TASK is your task or workflow. Other elements are self explanatory.
..
Data: lt_input_container TYPE TABLE OF SWR_CONT.
..

l_container-element = 'START_DATE'.
l_container-value = is_event-EBEGD.
append l_container to lt_input_container.

* start the workflow
CALL FUNCTION 'SAP_WAPI_START_WORKFLOW'
EXPORTING
TASK = c_wf_task
LANGUAGE = SY-LANGU
DO_COMMIT = 'X'
USER = SY-UNAME
START_ASYNCHRONOUS = 'X'
* DESIRED_START_DATE =
* DESIRED_START_TIME =
IMPORTING
RETURN_CODE = l_return_code
WORKITEM_ID = l_workitem_id
NEW_STATUS = l_new_status
TABLES
INPUT_CONTAINER = lt_input_container
MESSAGE_LINES = lt_message_lines
* MESSAGE_STRUCT =
AGENTS = lt_agents
.

2. No idea..
3. This program can be send a link to the portal if you do not have a
SAPGUI at managers desktop. You need to maintain a new text with link
init. Text can be maintained using se61 and use it in RSWUWFML for
'Dialog Text'.

4. Normal object programming, I have used the 'result parameter'. I have
not done it through BSP application. To populate a table container, just
append the same container name with your individual table entries. Then
in the workflow, it will appear as table container.
l_container-element = 'AGENTS'.
l_container-value = 'USXXXXXX'.
append l_container to lt_input_container.
l_container-element = 'AGENTS'.
l_container-value = 'USYYYYYY'.
append l_container to lt_input_container.

Hope it helps.
