| # Types of exception messages Each exception message is a token of a certain exception message type. Types and categories The following categories of exception message types can be distinguished: Inventory and demand exception messages Order exception messages Pegging exception messages Resource exception messages Error exception messages Resource exception messages are stored and retrieved per resource. You can view and print resource exception messages in the Exception Messages by Resource (cprao1130m000) session and the Print Exception Messages by Resource (cprao1430m000) session. All other exception messages fall under the generic label of item exception messages, because they are stored and retrieved per item. You can view and print item exception messages in the Exception Messages by Planner and Item session and the Print Signals by Item/Planner (cprao1425m000) session. Note Although all errors are considered item exception messages, some types of error exception messages do not refer to a specific item. For these exception messages the item field remains empty. This holds true for the following error exception message types: Fatal Error No Items for Plan Unit The following item exception messages can also be generated for channels: Actual Demand Late Forecast <> Actual Demand No Demand (Master Plan) When exception messages are generated Item exception messages as well as resource exception messages are generated when you: Run a exception message update using the Update Exception Messages (cprao1210m000) session. Initialize or maintain a scenario by running the Initialize, Roll, and Update Scenario (cprpd4200m000) session. Run master-based planning Run order-based planning Only resource exception messages are generated when you: Rebuild the resource planning by running the Rebuild Resource Planning (cprmp3200m000) session. Update the resource planning in the Resource Master Plan (cprmp3501m000) session. Update the resource exception messages in the Exception Messages by Resource (cprao1130m000) session. When you update your item exception messages in the Exception Messages by Planner and Item (cprao1125m000) session, only item exception messages are generated. Some types of item exception messages are also generated when you run the Convert Master Plan to Planned Orders (cprmp2240m000) session. Master planning and order planning To a certain degree, master planning and order planning differ when it comes to the exception messages generated. Some item exception messages are typically generated when LN creates or updates an item master plan, whereas other item exception messages are usually created in the context of order planning. Example Order exception messages are mostly generated in order planning, while demand exception messages are usually generated in master planning. Inventory exception messages, on the other hand, are created in both types of planning. Note When LN generates or updates planned orders, the item master plan for the item involved is checked as well. Running the Generate Order Planning (cprrp1210m000) session, for example, not only yields item exception messages typically belonging to order planning, but can also produce item exception messages which are usually confined to master planning (such as demand exception messages).
