3425677 - Monitor Purchase Requisition Items filter 'Created By'

It is possible to filter a work list using the 'Created By' field in the 'Monitor Purchase Requisition Items' APP. 
To do so a user would include the 'Created By' as a filter criteria and enter the CB number of the user to search for their Purchase Requisitions.
Sometime search by the user description works and sometimes only the CB user works.
