Common Model Groups are typically used across multiple feed types to enrich extract data.
Common Model Groups are not standalone objects and cannot be extracted or loaded individually. They are actually small collections of fields that are often useful to include in an extract that usually would not have these fields. Each model group is controlled by a specific parameter and is only present in the extract if the control message (RTR) contains the corresponding filter. The filters that control the presence of these groups in extracts, and the feed types that are used to initially load the data contained in each model group, are indicated next to each model group.
More detailed information about which parameters control the level in which each model group is included can be found on the Control Message Required and Optional Parameters page.
