Occurrence elements

The following table lists elements of the product structure that are relevant to occurrences, absolute occurrences, and managed occurrences. Element Purpose Absolute occurrence A relationship between a parent assembly and an item one or more levels lower in the structure. The parent assembly is the context in which the absolute occurrence exists. You can define data on the absolute occurrence that overrides the data stored on the item when you select the context assembly and view the structure. Both relative occurrence data (notes and transforms) and attachments can be overridden with data on absolute occurrences. Each absolute occurrence can have one or more unique attribute values that distinguish it from the other absolute occurrences derived from the same single occurrence. Occurrence (relative) (Sometimes called relative occurrence.) A hierarchical structure relationship between the immediate parent assembly and its child component item (in an imprecise assembly) or item revision (in a precise assembly). You can use a find number to identify for an occurrence, but this number may not be unique. Data can be stored on the occurrence, including occurrence notes and transforms.
