How to Implement Purchase Requisition Approval based on Category and Cost Center

Content

We have a business requirement where the Purchase Requisition approval should be done on the basis of category and then through cost center. for example,

If a purchase requisition has been raised with category "Safety" then it should be approved first by safety and then once approved it should follow the cost center and will be approved by cost center manager then. So to get the Purchase requisition finally approved there are two-stage - first it should be approved by the Category manager and then it should go for approval to the Cost center manager.
