1) A specific SKU (Material number) is used by 2 different parts of the business (it is sold as a spare part and it is used to repair units in house). Hence, this part has primary and secondary requirements (Independent & dependent demand). The inventory is kept separate in 2 different bins/locations. The challenge is to plan the replenishment of this material in MRP. MRP will look at the combined requirements and generate one Purchase Requisition that in turn is converted to a Purchase Order, which then is received (in bound). The problem is that if we want to keep them separate in storage we need to somehow separate the inventory. Is there a way to get MRP to plan this material separately depending on the source of the requirement? I would not want to create a separate Plant to do this.
2) The other question is as follows:
I have 3 plants, I have inventory for a given SKU at each of the plants. The forecast however is at a u201CPlanning Plantu201D (4th plant) at an aggregated level for all 3 plants and I want to carry out a MRP calculation at the planning plant to determine how much I need to buy (purchase Requisition) for all 3 plants combined.
I would really appreciate your input on this.
