Passing parameters to Workflow.

Former Member — Fri, 09 Sep 2005 10:32:14 GMT

Hi!

I m passing values from my ABAP prog to my event container and from there to my workflow and ultimately to my workitem text.

Now my problem is - my ABAP prog. is passing junk characters along with the actual value to my event container parameters while setting event parameters thru

swc_set_ELEMENT ev_container 'EVENT_PARAMETER' VALUE.

How to prevent these junk chars from being passed?

Sudipto,

If you are on a release higher than 4.6, find the SAP_WAPI_xxxx function module to create the event. You don't have to use the container macros with the WAPI FM. Otherwise post the relevant pieces of your code.

Cheers,

Ramki Maley.

Thanks.

But I am using SAP_WAPI_CRATE_EVENT. Anyways find herewith the relevant code.

Here I am catching the saved doc no. and then based onwhich retrieving relevant data and passing it to the event contaner parameter. But along with the actual value certain other values r also passed. My actual value is in EVENT_CONTAINER-ELEMENT -VALUE (Can be checked thru debugging)

Hi Sudipto Barman,

I'm not sure but it looks like there is a problem with the Macros, though nothing apparently.

Try this: The data type of containers is an internal table of type SWCONT just populate this manually and pass it to INPUT_CONTAINER in the function call.

And remeber to trim the charecter fields using condense no-gaps wherever necessary.

Good luck,

Sudipto,

for the WAPI FM the container is a simple internal table. You simply fill the internal table with the Element name and its value using the APPEND statement. Please see the structure of the input_container parameter of the FM. You should not use any of the macros.

I do not want get into a discussion of your design but It is strange that you are supplying the object key as a literal.

Cheers,

Ramki Maley.

Hi Arun!!!

Nice speaking to u yesterday. But still I cudn't solve the prob.

I tried ur sugg. .ie. appending the event container with my element name and value, but still it didn't solve the prob. Anyway thanks.

Has anyone faced any similar scenario n how did u tackle it?

Regards,

Sudipto.

Re: Passing parameters to Workflow.

ramki_maley — Wed, 14 Sep 2005 11:32:09 GMT

Did you declare and fill the Container as below (see my earlier reply above)?

DATA:

ev_container like swr_cont occurs 0 with header line.

ev_container-element = 'TPLNR'.

ev_container-value = LTPLNR.

append ev_container.

ev_container-element = 'PLTXT'.

ev_container-value = LPLTXT.

append ev_container.

Cheers,

Ramki Maley.

Hi Ramki!!!

Thanks a lot. But still my prob persists.

Actually what's happ'ng is:

ev_container is of type SWCONT. Now fields of SWCONT r ELEMENT, TAB_INDEX, ELEMLENGTH, TYPE and VALUE. So the data being passed to WF workitem is with these values i.e.

if actual value to be passed is 'RAMKI'.

it is passing 000000010CRAMKI.

Cud anyone guide me on solving this?

Thanks n Regards,

Sudipto.

Re: Passing parameters to Workflow.

ramki_maley — Mon, 19 Sep 2005 12:02:09 GMT

Sudipto,

Let me know if you have done the following:

Defined the Event parameters for the object in SWO1.

Defined the WF container elements with same properties with the Import & Export boxes checked.

Defined Event Parameter to WF Container Element binding on the WF template.

Triggered the Event with the correct parameter names using the WAPI as described in my previous reply above. Once again if you are using the WAPI you must fill the container parameter as specified. The WAPI converts the simple Internal table to SWCONT format and passes it to WF.

If you are then trying to access the container element in an Object method or a check/receiver FM, you then use the container macro SWC_GET_ELEMENT to read the value.

Cheers,

Ramki Maley.

Hi Ramki!

Thnx.

Actually my Workflow is just receiving the values from the event parameters and populating the same in a send mail task.

Event parameters r getting values from the screen in my ABAP prog. which is actually triggering my event.

Now I m getting those xtra values of SWCONT table passed to my event parameters in my workitem.

And Ramki this is why, in another WORKFLOW, I m unable to use the EXPRESSION for agent assignment as my workflow cont. element has userid + SWCONT xtra values.

Dont know how to get rid of those xtra values? Cud u plz. help?

Thanks and Regards,

Sudipto.

Please repost your event triggering code if you made the changes.

Hi,

Please see the lines I commented in italics, my additions in bold.

EVENT RELATED DECLARATIONS----

data: event_Creator like swhactor, "HOlds event creator's login id

jeventid like SWEDUMEVID-EVTID, "Return parameter given Event ID

ev_container like swr_cont occurs 0 with header line.

EVENT RELATED DECLARATIONS----

event_creator-otype = 'US'. "US stands for SAP User

event_creator-objid = sy-uname.

* DO NOT USE MACRO. Container parameter is an internal table.

* Use append statement

*** swc_set_ELEMENT ev_container 'CUST_DATE' DATE. "Set event

"Container

ev_container-element = 'CUST_NAME'.

ev_container-value = CUST_NAME.

append ev_container.

This should solve both of your problems.
