WIP_PICKING_PUB.ALLOCATE FAILS ON CREATING MOVE ORDERS

Hi , We are using the standard API(wip_picking_pub.allocate) for creating the move orders. we are passing the released status jobs to the API.If the API is throwing the l_return_status='E' or 'N',then the subsequent jobs that are passsed to API are not getting created and returns l_return_status='E' for all the jobs which are elgible for creation of move orders. This is a critical issue and business is unable to do transactions. Please provide the solution at the earliest.
