1. Go to Managing My Area work center
2. Choose the Approvals view
3. Choose the Purchase Order ABC
4. Choose the Approve buttonnow the system throws an error message as Action not enable.

The Purchase Order was ordered with the Sales Order assigned to it and then the Purchase Order went in to In Approval. When the Purchase Order was In Approval, the Sales Order was completed. The user is trying to approve the purchase order after the sales order that was assigned to it was completed. This is the reason why the Approve action is failing for the purchase order. 

As a work around you can assign the purchase order to the different Sales Order which is Open/In Process status and then approve the Purchase Order.
