Function module - object - workflow(complicated to explain:))

Question

Hello,
I have a problem.
I created in se37 the function ZRR_ACTORS. I have as the import parameter PRNUMBER with type BAPIEBANC-PREQ_NO. As an export parameter i have RECIPIENT with type BAPIEBANC-REASON_BLOCKING( i have not found an appropriate type for the recipient that works in a function module for the object, so i used this..i do not think that is the problem).
The code is:
data:begin of gs_eban,
  menge type eban-menge,
  preis type eban-preis,
  end of gs_eban,
  gt_eban like table of gs_eban,
  gv_sum type i,
  gv_aux  type SWD_MRCPNT.
select menge preis from eban into TABLE gt_eban where banfn = prnumber.
loop at gt_eban into gs_eban.
  gv_sum = gv_sum + gs_eban-menge * gs_eban-preis.
  endloop.
if gv_sum > 20.
    select single recipient from zteam_approvers into gv_aux where zuser = 'xxxx.
    else.
    select single recipient from zteam_approvers into gv_aux where zuser = 'yyyy'.
      endif.
recipient = gv_aux.
As you probably see, i am sending this function the purchase requisition number. In the function I am calculating the value of the purchase requisition. If the value is bigger then 20 i want the recipient to be the email adress of the user xxxx. Else the other email. zteam_approvers is a table with users and their emails.
When i test this function everything is ok.
I created subtype for object BUS2015(purchase requisition), called ZBUS2015. Here i created a method which uses the function ZRR_ACTORS. I released it and after that i selected in swo1 BUS2015 and delegated ZBUS2015. So now when i test object BUS2015, i can use method ZRR_ACTORS which contains the function module ZRR_ACTORS.
If i test this object, the method ZRR_ACTORS works fine. I give the method the number of the purchase requisition and it returns me the user xxxx or yyyy.
Now, i created a workflow. In this workflow i want to send an email to the user xxxx or yyyy. So i have to execute the function ZRR_ACTORS. I create an activity(zrr_activity) in the new workflow. In it, i create a new task(zrr_task) in the activity with object category BUS2105 and method ZRR_ACTORS. I am setting this method as a background method, because after the execution of the function i want to create a Send email step, with the recipient being the one of the emails.
My problem is the binding. In the workflow container i set the PRNUMBER as an import parameter and the Recipient as an export parameter.
In the binding of the step(zrr_activity) i set the following bindings:
Workflow                           STEP
&PRNUMBER&  ->  &PRNUMBER&
&BUS2105&  ->  &_WI_OBJECT_ID&
&RECIPIENT&  <-  &RECIPIENT
If i click in the activity, in the task i created(zrr_task), in the object method i set the bindings:
Task                                 Method
&PRNUMBER&  ->  &PRNUMBER
&RECIPIENT&  <-  &RECIPIENT&
I run the workflow. Now i enter the PRNUMBER 0010000420, but it remains 10000420 (maybe this i because of the type PREQ_NO.) and execute.The task has the status In Process. I click on Workflow log, then on list with technical details, and then in the container, i see the Recipient is empty.
So, i think the function did not work properly. What do you think?
Thank you very much,
Efren

Hi Efren,
Go to transaction ST22 and check for any dump.
The work item is in process, so there will be a dump in the system.
The Function module parameters could be a problem.
ST22 transaction will give you details about the dump.
Thanks,
Viji.
