ChangePairView & ChangePairMasterView reference

The ChangePairView and ChangePairMasterView are parent-child lists of all changes (parent), as well as items on their Affected list (child). The view is a side-by-side set of the change form attributes; a single affected item's attributes; and the change/affected item relation attributes for released and canceled iterations. The parent change form may have zero, one, or many affected item child records, which determines the number of rows in the view.

The ChangePairView is based on the ChangeView and ItemView lists, and excludes custom attributes from the change form and affected items. The ChangePairMasterView is derived from the ChangeMasterView and ItemMasterView lists, and includes custom attributes.

The affected item always reflects the most current item data, as obtained from the ItemView and ItemMasterView lists. Therefore, only the most recent change pairs indicate the affected item's current iteration; earlier change pair views accurately reflect the items (class, owner, type, number, etc.) that were affected, but not the actual iteration that was released or canceled. To obtain non-current change data that includes the actual released or canceled iterations, use a custom SQL query based on the [AffectedItem_View] and related non-public views.

Column definitions §

There may exist in the view one or more "housekeeping" columns that have been reserved for PDXpert's private use. These columns' names begin with the prefix HK (for instance, HK1). Housekeeping columns may be redefined or eliminated in a future PDXpert release without notice. These are not documented, and you should ignore these columns in your own SQL queries. Do not create any custom attributes that use the HK prefix. You may want to create a user-defined view that excludes the housekeeping columns.

The column ordering may not be exactly as shown in this table, and may change in a future PDXpert release. Use the column name, not ordinal position, in your SQL queries.
