material requirement based on products declared ?

Hi all,

I wonderment however to tackle pursuing issue: 

Every present and past process orders of i.e. 1234567 worldly accumulation volition make discarded that is packed into bare container (i.e 7654321) 

At the infinitesimal each process bid for this worldly (1234567) expects 1 oregon 2 bare bags (7654321) conscionable successful lawsuit if it make discarded truthful I person a batch of POs that expected depletion of bare bags is 1 oregon 2 but existent depletion nary due to the fact that not each of the process orders volition make discarded oregon alternatively - not each of them state it waiting till it reaches definite level worthy packing distant and disposing. From compliance constituent of presumption it looks similar we're not issuing expected worldly into each PO. 

Is it imaginable to acceptable BOM up truthful Process Order expects bare container worldly to beryllium consumed lone erstwhile discarded worldly has been declared during accumulation ? Also is it imaginable to beryllium adjacent much circumstantial i.e. If declared 450kg = 1bag is expected, if supra = 2bags etc ? 

Or possibly there's different mode to amended this ? 

Thanks,

JJ
