Routing Time Card Approval Workflow based on Time Entries

Summary

I have a requirement where Time card approval should be driven based on the time entry entered in the time card

Content

there are a set of payroll time types that need to be approved by the head of the department , if payroll time type is Regular Hours then the time card can be approved by the Line manager? 

 

Example: If the time card is having Regular hours and Overtime then the time card should be approved by Line Manager then Head of the department.

Questions :

- Which Attributes allows me to build my logic in Payroll Timecard Approval? - Please note that I found and attribute in Workflow approval called Payroll time type, but this attribute is not working with me.
