Is it possible to create one to one requisition - Purchase order with auto create from by selecting

Our Business requirement is buyer should be able to select multiple line that belongs to different requisitions at a time on Auto Create from (mass selection) and create individual purchase orders (one Requisition - One Purchase order). To meet this requirement we tried the following option on Auto create from and an error occurred at the time of creating PO.

Steps;

1. Buyer will log-in to oracle purchasing and navigate to auto create.

2. Will Query for all Approved Purchase requisitions with selection criteria as Buyer

3. Selects all requisitions by using 'Select All' functions from Edit menu on auto create form

4. Change the grouping from default
