When master scheduling processes demand for a BOM version, the following method is used to identify which warehouse to use for each BOM line.

• If the Work center consumptionfield on a BOM line is selected, the program uses the route that is associated with the item to trace the warehouse. The route's operation is assigned to a work center group. If the work center group is associated with a production unit, the production unit may state a default picking warehouse to use.

  Note
  When the multisite functionality is activated, the program uses the route version that is associated with the site.

  If a warehouse is not found using the route, the program uses the item's master data to identify the warehouse. The program prioritizes which warehouse to use in the following order:

  • The default warehouse that is defined for the item.

  • The default warehouse that is defined for the site.

• If the Work center consumptionfield is not selected, the program uses the warehouse that may be defined in the Warehousefield on the BOM line.

  If a warehouse is not defined on the BOM line, the program uses the default warehouse that is defined for the item.

• If a default warehouse is not defined in the item's master data, the warehouse is determined using the inventory dimension settings that are defined for the item. The rules are:

  • If the warehouse dimension is not set to mandatory for the item, a warehouse is not required. The demand explosion proceeds to the next BOM line or the next demand.

  • If the warehouse dimension is set to mandatory for the item, the demand explosion stops because the required warehouse data does not exist. No additional requirements are created for this item, and no additional BOM lines are processed until the user enters the required warehouse information, either on the item's data or on the BOM's data.
