Time Management: FMLA Workbench issue

Hello:

We are using SAP 6.0, and implemented the FMLA Workbench last year at Go-live; however, we still do not have complete functionality for employees on UNPAID Leaves of absences. The problem is that our business process requires us to create an unpaid LOA action, which skips IT2001 so no absence types are used for the employees. They are on an INACTIVE payroll status, and our HR benefits interfaces are configured as such (and employee needs to remain on INactive payroll status).

We are exploring a way to enable the unpaid absences to flow into the Workbench, so can someone tell us how we set up the absence type time constraints so that we can enter an unpaid absence type for a person in inactive status? Has someone had similar experiences?

Thank you.
