I am facing a unknown problem of packing of po not posting into transaction second time. I mean i created a po of 100 and posted first packing slip with 10 quantiy which is affecting inventory whereas next packing slip with any quantities is not effecting but systems shows the packing slips. One more observation was that after first packing slip posting, on order line in transactions is not showing. Any ideas or solution will be appreciated. Please help me on this.
