Workflow instances problem

Question

My problem is that in workflow i am sending workitem for manager approval.If manager rejects the workitem it goes to employee back for correction and resubmission.But what is happening once workitem is send to employee for correction the current workflow instance is completed and when user changes the report and resubmits it a new workflow instance will be created.This all increases load on the working system.
Can we keep the same workflow instance working till report is rejected or accepeted and then only workflow instance is completed.

Answer 1

I think you can make use of Function module
SAP_WAPI_WORKITEMS_TO_OBJECT
in a virtual attribute that will check whether any existing wflow is already triggered for it. If yes set the Flag(Virtual attribute) value as X. Make use of this attribute in th Start ciondition of the wflow in SWB_COND Tcode.
Now in your workflow the approval step should be inside a loop that loops until the request is approved. Inside the loop the approval step should be in fork with 2 parallel branch and 1 necessary. In 1 branch put approval step and in other branch put the Wait for event step.
