In this post, I'll discuss about the recent issue of multi-step human task approval workflow. The scenario belongs to issue of a multi step user task approval where the request was initiated by Oracle IDAM and workflow being fulfilled using Oracle SOA. Below is the summary of the use case- Environment Oracle Soa Suite 12c, Oracle IDAM 12c Problem There was a two step approval process where approval request was initiated from Oracle IDAM system (OIM). All user base resides in OIM system at LDAP/DB level. Dynamic user assignment was there to act on user task.

The task assignment was being done using business rules. So, changes done and the composite was deployed and tested out. The approval flow was fine up to level 1 but after approval by level 2 (any group member) it shows the wo

In this post I'll describe about the business scenario where following requirements came for human task assignment in SOA suite 12c- Environment Oracle EISS (Enterprise Identity Services Suite) consists of a bundle that contains SOA suite with IDAM for workflows management. Scenario The current scenario involves 2 level approval of a task where approval request was processed in serial mode i.e. participants of task were in serial mode. Users at level 1 & 2 were identified dynamically and business rule was enforced for task assignment. Business Requirement Human task approval level 1 should be assigned to a single user and approval level 2 shoud go to a group rather than a single user. Once approved from level 1 the task should be assigned to a group of N members where each member can see the task in their inbox (in worklist app).
