Configuring structures by occurrence effectivity
Setting the date for occurrence effectivity
Teamcenter configures the occurrence effectivity by the date defined in the current revision rule. Teamcenter uses an explicit date entry, if the current rule contains one. If the rule has no date entry, the effective date defaults to today, but you can manually set a different date using the Tools→Revision Rule→Set Date/Unit/End Item menu command.
You can choose to show only the configured occurrences, or all occurrences. You can toggle this setting by choosing View→Show Unconfigured by Occurrence Effectivity. If you display the EOC - Effective Occ. Config'd column in the structure properties, occurrences that are configured show a Y. If the occurrences are not configured, the column is blank.
Occurrences are configured if:
The effectivity range encompasses the date specified by the current revision rule.
They have no effectivity object. Such occurrences are always configured, regardless of date.
