Workflow work items not generating

Hello Team,

I am trying to create PoC for my client and I am new to Workflow but extensively worked in ABAP.

Actually in our system the existing workflows are running fine.

I have created Standard task with the below details

In Basic tab i have given

Object Type          BUS2034

Method               DISPLAY

Triggering event I have given like

Terminating event

I have done the binding & activated event in triggering event tab.

And I have checked in SWE2, so 2 new entries are added

I tried to test using SWUE but work item not created

I tried to changed Sales contract using VA42 but work items not created

I have tried from custom program

CALL FUNCTION 'SWE_EVENT_CREATE'

   EXPORTING

     objtype                       = 'BUS2034'

     objkey                        = '0040014284'

     EVENT                      = 'CHANGED'

But not created work item(have checked in SWI1 and SWIA)

SWU3 configuration are okay since the existing workflows are running in Development system.

How to find the rootcause why the work item not created(I agree there is no agent but work item should be created as my knowledge)

How to test the sequence(what are the tcodes) which place its failing.

I have to proceed further steps in PoC if the above problem resolved.

Regards,

Vadamalai A
