to combine execution of two dialog steps.

[Vinod Ramchandani]

Hello everybody..
 
I want to combine the execution of two dialog steps to one.
I have two different activities in workflow, need to be performed in one GO.
 
I have Buyer in Requisition Approval Workflow.
Buyer will approve the requisition and then create the PO from the
requisition.
 
right now, buyer will have first workitem that will ask him to approve the
requisition.
once buyer will approach to that workitem and approve the requisition then
he will get another workitem which ask him to create PO from the
requisition.
 
If Buyer approves then he needs to navigate to the Inbox and then he
requires to press refresh button then he will able to get the workitem to
create PO.
 
I need to combine above mentioned two dialog step activity in to one.
can it be possible to do so?
 
Usually, Decision step and any other acitvity automatically been combined to
one.
( If step property of the activity have "step not in workflow log" -
checked, otherwise we will get two separate workitems,still we have One-GO
execution of the same.)
 
I need similar execution in two different activities like i have mentioned
above.
 
can anybody have some idea to achieve the above functionality without
combining the business object methods?
 
i really appericiate your valuable inputs.
 
thanks and regards,
vinod ramchandani.
