Critical items
An item that you define
		as critical is one that can cause a bottleneck in a production process, such as
		an item with a long or uncertain lead time.
How to define a critical item
- Create an item in the Items (tcibd0501m000) session. You can also create the item using Engineering data management summary.
 - Define the item as a plan item in the Items - Planning (cprpd1100m000) session. You can zoom to the Items - Planning (cprpd1100m000) session from the Items (tcibd0501m000) session. You must define an item as a plan item,
		  before you can define it as a critical item. Note the plan level of the plan item. You must use the same plan
		  level for the critical item.
 - In the Items - Planning (cprpd1100m000) session, select the Critical in Master Planning check box.
 
A critical item can be
		either Manufactured or Purchased.
How to use a critical item
To define relationships between plan items and critical items:
- Use the Bill of Critical Materials (cprpd3120m000) session to define the relationship
		  structure. The structure is similar to that of a Structure of a multilevel BOM.
 - Generate the structure
		  (that is, the critical bill of material) in the Generate Bill of Critical Materials (cprpd3220m000) session.
 
You can print the
		relationships you have defined in the Print Bill of Critical Materials (cprpd3420m000) session.
You can use master planning to plan the
		requirements of critical items.
