If you can, group on the the unique identifier for the requistion, likely a table.requistionID field.
you can suppress the GH and GF if desired
Inside that group you can insert a summary as the maximum of the 'accepted date' field.
Now you can use this condition in a running total.
in the evaluation options you can select 'use a formula'
maximum(table.acceptedfield,table.requistionID)=table.acceptedfield
This measn that the Running total you create will only run on a field where this condition = true
