Component Pick Release Batch

Hi,

Has anyone here already tried to create a custom package that uses WIP_PICKING_PVT to release a batch of Discrete Jobs?    For some reason, I can't seem to make this work :

l_count := l_count + 1; := l_count + 1;

l_alloc_tbl(l_count).wip_entity_id := v_wip_id;

l_alloc_tbl(l_count).use_pickset_flag := 'N'; (l_count).use_pickset_flag := 'N'; l_alloc_tbl(l_count).project_id := NULL; (l_count).project_id := NULL; l_alloc_tbl(l_count).task_id := NULL; (l_count).task_id := NULL; wip_picking_pvt.allocate(p_alloc_tbl => l_alloc_tbl
