Run by Company or Warehouse
Choose one of the following: Run by Company: Consolidate existing inventory, demand, and supply into default warehouse only. To run the MRP calculations on the company level, select this option. SAP Business One calculates demands and supplies jointly for all the selected warehouses. To do so, the application sums up all the initial inventory quantities, demands, and supplies of the selected warehouses, and then consolidates all the quantities into the default warehouse for requirements calculation. Run by Warehouse: Include existing inventory, demand, and supply separately for each warehouse. To run the MRP calculations on the warehouse level, select this option. SAP Business One calculates requirements separately for each warehouse. By default, the application selects the three checkboxes (Include Existing Inventory, Include Demand, and Include Supply) in the grid for all warehouses except non nettable warehouses. You may manually select the non nettable warehouses if necessary. Your definition here may affect MRP calculations for inventory level and demands raised by inventory level requirements. For more information, see Inventory Level in MRP Wizard, Step 5: Documents Data Source.

Include Existing Inventory
To consider the existing inventory quantities of this warehouse in MRP calculation, select this checkbox.

Include Demand
To consider all sources of demand from this warehouse, including requirements from the inventory level in the MRP calculation, select the checkbox. Note Supplies with negative quantities are regarded as demands. For example, a purchase order is typically a source of supply. However, if the purchase order has a line with a negative quantity, then this line is included as a demand. If you deselect the checkbox, the MRP does not consider inventory level requirements for this warehouse, regardless of your inventory level definition in MRP Wizard, Step 5: Documents Data Source. If you deselect the checkbox, and there are items in this warehouse that happen to be child items in a bill of materials (BOM), the planning for the parent item of the BOM may encounter problems because the demands for child items (from parent items in the BOM) are not included in the MRP run. In such a case, you receive a message stating that recommendations are not generated for this parent item due to components defined in the BOM structure whose demand is not included in this MRP run. You can change your settings for inventory date source and run the MRP again. End of the note.

Include Supply
To consider all sources of supply in the MRP calculation, select the checkbox. Note Demands with negative quantities are regarded as supplies. For example, a sales order is typically a source of demand. However, if the purchase order has a line with a negative quantity, then this line is included as supply. End of the note.
