 - Item level (See To search sourcing strategies).
 
Use the following procedure to enter a sourcing strategy on cluster level:

Use the following procedure to enter a sourcing strategy on item group level:

           Note: 
           
         If a plan item has no valid supply strategy, LN uses the following values by default:

 - Allocation rule: Percentage
 
You can specify different rules for external and internal suppliers.
