You can use severities to determine how severe the impact of a change on an engineering change order is or can be. To (automatically) calculate the severity of an engineering change order, set up severity rule sets. For each severity rule set, define the rules that must be met to apply the related severity.

You can add these rules to a severity rule set: 

  • Route change (triggered by any change made to routes)
  • BOM change (triggered by any change made to BOMs)
  • Document change (triggered by any change made to documents)
  • Attribute change (triggered by any change made to engineering attributes)
  • Impact change (triggered if the Impact is changed to New version or New product)

On (automatic) calculate, the severity rule sets are checked from top to bottom. The first severity rule set for which all defined rules are met determines the severity.

Usually, you put the severity rule set with the most rules at the top, and the one with the least rules at the bottom of the list. Use the Up and Down buttons to define the sequence in which the severity rule sets are checked. 

Example: 
You have three rule sets: "High", "Medium" and "Low"
  1. High: Route change, BOM change, Document change, Attribute change, Impact change
  2. Medium: Route change, BOM change, Document change
  3. Low: Document change

Scenario 1: An engineering change order has changes to the route, the BOM, and the document. On calculate, the severity is set to Medium.

Scenario 2: An engineering change order has a change to the document. On calculate, the severity is set to Low.

Scenario 3: An engineering change order has changes to route, BOM, document, attribute, and impact. On calculate, the severity is set to High.


Standard procedure

1. Go to Product engineering > Setup > Engineering change management > Severity rule sets.
2. Click New.
3. In the Severity field, select one of the predefined severities.
4. Click Add.
5. In the Rule field, select a value.
6. Close the page.
