| 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 Item - General (tcibd0101s000) 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 Item - General (tcibd0101s000) 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 - Ordering (tcibd2500m000) session, select the Critical in 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.
