Hi Gopi,
Today we had same issue as you had earlier and message was "Approval or Rejection of this requisition is still in process, you can refresh the list of requisition manually".
As you suggested we need to implement the SAP Note 2201883, and till this its fine.
but my doubt is "Do we need to implement the BADI for standard workflow" ?
could you please suggest me on my new thread Purchase Requisition Informative message appear while approving ?
so i would be able to give point to you .. thanks in advance !
Thanks,
Brajesh
