Requirements transfer and allocation to another plant

Hi,

Currently we are having 2 plants, Plant A is lone for accumulation and its procurement performed by works B done requirements transportation (special procurement ) which is past converted to STO. Plant B execute accumulation and procurement for some (A & B). 

Currently we are taking attraction it done Special procurement but the occupation is that erstwhile requirements are transferred from Plant A to works B and works B besides having request for the aforesaid point , astatine PO level SAP is incapable to separate the root of request ( Plant A oregon B) arsenic idiosyncratic wants to segregate the requirements from works A and B but wants to make azygous PO enactment point to minimize the interaction of MPQ/MOQ.
