Changing Operation Numbering
Windchill MPMLink numbers operations in sequential increments of 10. For example operation 10, operation 20, and so on. However, you may wish to configure your operations so that automatically increment by a different numbering scheme.
To change numbering schemes you can modify the following properties:
wt.operationLabelIncrement
wt.operationLabelNumberOfCharacters
For example, to have operation labels with three characters and which are increased by 5 (005, 010), put the following in site.xconf, and then run xconfmanager -pF:
<Property name="wt.operationLabelIncrement" overridable="true" targetFile="codebase/wt.properties" value="5"/>
<Property name="wt.operationLabelNumberOfCharacters" overridable="true" targetFile="codebase/wt.properties" value="3"/>
Additionally, to change the padding that an operation uses (for example, to something other than 0), modify the following property:
wt.operationLabelPaddingCharacter
