Location - Manual Entry in the Sales Order
When a sales order is entered in SAP CRM, the location from which the item is to be delivered is determined automatically using location determination. (See also Location Determination in the Sales Order)
However, in exceptional cases, you may need to overwrite the location, so that the availability check is carried out in this manually-specified location first.
Prerequisites
Other prerequisites are listed under Location in the Sales Order.
Features
When the availability check is carried out, the manually-entered location is checked before the other locations based on rules are checked.
You have to store location-dependent product master data for the product. You can find more information in the SAP Library for SAP Supply Chain Management
under 
SAP Advanced Planning and Optimization (SAP APO)

.
Note
You can change the location for main items only.
You cannot change the location if checked deliveries exist for the item or one of its subitems.
Activities
The location is shown in the sales item in the field Vendor (Plant)
. If the system has already determined a location, overwrite it with the business partner for the new location. You overwrite a location when you create or change a sales order by entering the relevant business partner for the partner function Vendor (Plant)
. In this case, the availability check is triggered automatically. You can enter a location at item level only.
Note
Note that the input help for the business partners lists all business partners, and does not take into consideration whether a particular location is allowed for the product entered in the sales order item.
You can also ensure that the sales order items are shipped together from a single location by entering a consolidation location. For more information, see Consolidation Location.
