Exception Messages in Enterprise Planning

In Enterprise Planning, one way to monitor the performance of your planning involves the use of exception messages. These exception messages are used to indicate bottlenecks and other (possible) problems occurring in a specific scenario, and allow you to analyze and solve these problems.

Here are some key characteristics of exception messages:

  • Exception messages are created for a specific combination of scenario and plan level.
  • Each exception message belongs to one of a number of exception message types (for an overview of the available exception message types and their meanings, see the Related topics).
  • The signal itself is a brief description of the problem or situation involved. The exception message can contain extra information, such as a relevant date, or an error specification.
  • Attached to each exception message are a number of fields containing extra information, such as a reference date, information on the order involved, and a quantity indication. The meaning of these fields can vary per exception message type; for more information, see the help for these fields in the Planner/Item Signals (cprao1125m000) session and the Resource - Signals (cprao1130m000) session.

You can use the Update Signals (cprao1210m000) to generate or update planning exception messages based on the current planning situation. In the following situations, you can also let LN generate or update the exception messages online:

  • When you initialize or update a scenario (in the Initialize, Roll, and Update Scenario (cprpd4200m000) session)
  • When you run a master-plan simulation
  • When you run an order simulation

When a exception message is created, it is marked as directed to a specific planner. The following procedure is used to determine this planner:

  • When simulating orders using the Generate Order Planning (cprrp1210m000) session, you can specify (in the Planning Signals to Planner field) to which planner the newly generated exception messages are sent.
  • If you leave the Planning Signals to Planner field empty, or if the exception messages are generated starting from a different session, the planner defined for the plan item in question (in the Items - Planning (cprpd1100m000) session) is used.
  • If the Planner field in the Items - Planning (cprpd1100m000) session is empty, the exception message is not marked for a specific planner. In sessions which give an overview or list of exception messages, you can view such non-planner-related exception messages by leaving the planner ID field empty.
Note

exception messages are only generated if the exception message type involved is included in the exception message settings defined for the planner in question. You can define and view the exception message settings in the Signal Types - by Planner (cprao1110m000) session. Here you can define customized settings for each exception message type (and separately for each planner), to fine-tune the circumstances in which each exception message is generated.

The Resource Analysis and Optimization module contains several sessions to quickly analyze and resolve exception messages. Here are some examples of what you can do with these sessions:
