New Work Relationship Workflow Requirement

Summary:

Hi All,

We just had a requirement for 'New Work Relationship' approval workflow. And the requirement follows like,

If "Employee's current worker type IN ('C','N') and Proposed worker type == 'E' then approval should be fwd to a user."

The issue is we couldn't find anything so as to map the current assignment in the approval workflow list of attributes tried in BPM as well. And found something as "(Assignment.Worker Type != "E")" but it was of no use. And on top of this rule conditions, the requirement calls for us to take the payroll frequency also into consideration.
