To search sourcing strategies
You can define sourcing strategies and supply strategies on three levels of detail:
- Plan item
 - Item group
 - planning cluster
 
Note: By default, LN uses the most detailed
		  sourcing and supply strategy defined for the item.
      Example
Suppose a requirement for item A has been identified. Item A belongs to item group B and planning cluster C.
LN searches the applicable sourcing strategy as follows:
- If a sourcing strategy has been defined for item A, LN will use that sourcing strategy.
 - If no sourcing has been defined for item A, LN uses the sourcing strategy for item group B.
 - If no sourcing strategy has been defined for item A or item group B, LN uses the sourcing strategy for planning cluster C.
 
The same process applies to supply strategies.
