Requisition Workflow Role Actions

Hi All,

I was just wondering if anyone is using the Requisition Workflow role actions:

CANCHANGEALL- While the eProcurement requisition is in pending approval status, these roles are allowed to change any field on the requisition, including quantity and price, without restarting the approval process

CANCHANGEDISTRIB- While the eProcurement  requisition is in pending approval status, these roles are allowed to change any field on the requisition distribution without restarting the approval process

CANCHANGEHEADER- While the eProcurement requisition is in pending approval status, these roles are allowed to change any field on the requisition header without restarting the approval process

CANCHANGELINE- While the eProcurement requisition is in pending approval status, these roles are allowed to change any field on the requisition line ,except the quantity and price, without restarting the approval process
