Here you can select the inventory location from where the production order components are to be taken if you have not specified a location on a stockkeeping unit card. To see the locations that you have set up in the Location table, click the AssistButton to the right of the field.
This field, together with the Locations Mandatory field, is very important in governing how the planning system handles demand lines with/without location codes. See Planning with/without Locations.
Concerning production demand, the program will use the same location for components as the one stated on the production order. However, by filling in this field, you can redirect the components to another location. You can also fill in the Components at Location field on the stockkeeping unit card.
Note: If you often need to plan for demand at locations, it is strongly advised to use the Stockkeeping Units feature.
