The Object Numbering Property
The following traits exist for the property that controls object numbering in Windchill PDMLink:
The auto numbering properties are controlled by the Object Initialization Rules Administrator. There is a unique property that enables or disables auto numbering for each object type. Use the following as an example:
wt.enterprise.GeneratedIdentificationObject.ChangeOrderGenerator.number.format=WFN-ECN{GEN\:wt.enterprise.SequenceGenerator\
:WTCHANGEORDERID_seq\5\:0}
The auto numbering properties handle the following objects:
Parts
Documents
CAD documents
Managed baselines
Product configurations
Products
Change objects
Process plans
Resource groups
Process Materials
Skills
Tooling
Sequences
Enabling auto numbering allows the user to determine the starting number (change to Oracle Sequence), prepend the number with alpha characters, specify the number of characters, and specify the padding value.
The auto numbering properties are controlled at the site level.
The auto numbering property can be set on the Object Initialization Rules Administrator page off the Site menu.
