How to pull inventory from a specific storage location

Question

Hi guys,
I wonder how can i determine which storage location should we pull  the stock from ...

Thanks much

Answer 1

In addition to helpful hints from other experts, I would like to discuss on other three aspects:
1.  MRP Run:  This new storage loc is normally operated by production staff before issuing to production orders.  Therefore, some planners do not want to include this stock in the MRP Run.  You can do so by exclude the storage location from MRP (via configuration or material master - set to 1 - Storage location stock Excluded in MRP).  Alternatively, you can plan your replenishment via MRP run by setting with reorder point concept.  You can maintain reorder point and replenishment qty in MRP4 if you create at plant/stor.loc. level and set Sloc MRP indicator to 2 (Stor.stock planned separately).  Then when you run MRP, if stor.loc.stock falls below reorder point, reservration to transfer (311 movement type) is created.  This can be an alternative to the nex point I would like to mention.
2.  Replenishment:  If you want the production staff to plan replenishment themselves, you can use pull list (MF60).  With the certain setting in the MF60 variant screen, you can create the transfer from store to prod.sloc. or create manual reservation.  Pull list can combine requirements from many production orders, calculate net req. (prod.order reservation - current stock), and perform the replenishment for you. 
3.  ATP:  Your ATP for component can be set to check the stock at the plant level instead of sloc.level by configuration.  You cannot exclude some of sloc. if you check at plant level though. 
In terms of material master setup, besides Prod.Sloc.Location in MRP2, you can maintain the stock determination group.  Then, you can add more rules like first from consignment then own stock of sloc. A, then B, then C, for examples.
Hope it helps.
