JDE Workflow

Hi all

i am creating a custom workflow using JDE enterprise one ,i am trying to use the same technique of the advance base price workflow ie (multiple approval at the same time ) using p450303 (speed price approval application) in another workflow instead of workcenter

i was able to read from files f98860 ,f98865 and f98866 and display the data in my application but i amnot able to proceed the Workflow when the approved or reject action is taken

Does any one has an experience in this case any suggestions
