change order request Requisition

Hi,

We customized our requisition workflow using AME rules.

So for the document type 'purchase requisition' the approval workflow is set to 'xxAME_requisition'

The requisition approvals are working fine.

Now,

the 'change order request Requisition' is not working ?

We want the change order request requisition to work exactly same as requisition approvals.

Do we need to customize it again ?

Or

If if i set the document type ''change order request Requisition' to the approval workflow 'xxAME_requisition', do it work exactly same as requisition approval ?

Please give more details on the change order workflows.

thx

Megan
