How to Initiate Demantra Workflw from EBS SPP ?

Question

Hi ,
I need to know ;
1. How to kick start a "Demantra Workflow " from within EBS ? ( A step wise approach is appreciated) ( opening Demantra workflow manager and manually doing starting is workflow is not an option for me)
2. When we kick start the workflow from SPP , I need to pass a parameter to the workflow ( the first step of workflow is a Stored procedure Step) , Is that possible , and how to do that ?

Answer 1

Hi,
Please find the answers inline
1.We can use the package utl_http.request to call demantra workflows from EBS. Develop a custom procedure similar to msd_dem_collect_history_data.run_load (this standard procedure has all the logic required to launch demantra workflow) and register it as a concurrent program in EBS which accepts workflow name as a parameter.
Using this concurrent program you can launch any demantra workflow just by passing the workflow name as a parameter to the concurrent program. No need to log in to workflow manager to launch a workflow :)
2.We can only pass arguments to workflow through methods but to use methods one needs to login to collaborator workbench , but to pass an argument from SPP(EBS) without logging into Workflow Manager or Collaborator workbench , you can follow below workaround
a.Hard the parameter in the workflow(procedure step) as P_PARAM
b.Accept the parameter which you want to pass to the workflow say ACT_PARAM from the concurrent program which launches workflow
c.update the table wf_schemas (this stores the workflow definition)
UPDATE wf_schemas
SET schema_data = replace (schema_data,'P_PARAM','ACT_PARAM')
WHERE schema_name='xx_workflow_name';
commit;
d.Launch workflow using the custom procedure developed to launch workflows
e.Rollback the changes done to the wf_schemas
Please try this workaround on a test instance thoroughly before progressing it to Prod.
Thanks,
Sudeep.
