Purchase Requisition Release Procedure Modification

Question

Hi
In Purchase Requisition Release, we have two deviations in business requirement from standard SAP behaviour:
1. In multistep release, system allows PR release to be revoked by a lower level release authorized person even though higher level release has been done. Example, PR Release has release codes A1, A2 and A3, A2 can revoke release even after A3 has released the same. How do I prevent this from happening?
2. If business requirement is to have release procedure based on item cost per unit and not on total value of the line item, how can this be achieved?
Appreciate any guidance on these issues
Thanks

Hi,
There is BADI ME_REQ_POSTED 
in method POSTED  you can write your code to trigger the workflow and get the information related to release strategy and
Purchase requisation  .
for more than one PR use below logic .
LOOP at im_eban into gwa_im_eban .
    concatenate gwa_im_eban-banfn gwa_im_eban-bnfpo into gwa_objkey .
  add data into container -----------------
      gwa_event_container-element = 'PurchaseRequisition'.
    gwa_event_container-value = gwa_im_eban-banfn.
    append gwa_event_container to gi_event_container.
    clear: gwa_event_container.
    gwa_event_container-element = 'ItemOfRequisition'.
    gwa_event_container-value = gwa_im_eban-bnfpo.
    append gwa_event_container to gi_event_container.
get the other details and create event to start workflow .
select single * from eban into lwa_eban where banfn = gwa_im_eban-banfn
                                              and bnfpo = gwa_im_eban-bnfpo .
        if sy-subrc <> 0 .
      call function 'SWE_EVENT_CREATE'
        exporting
          objtype           = 'BUS2009'
          objkey            = gwa_objkey
          event             = 'zcreated'
        tables
          event_container   = gi_event_container
        exceptions
          objtype_not_found = 1
          others            = 2.
ENDLOOP .
Hope this will resolve your issue.
Thanks and Regards,
