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. Initially, there was two level approval task where one user per level was assigned i.e. one user can act on a task. Later, the requirement changed as task assignment to group for level 2 approval.

The approval flow was fine up to level 1 but after approval by level 2 (any...
