Source System Validation and Integrity Checking Rules

During the validation process, all modified entities, which satisfy the selection criteria, are initially selected based on CCDB information. The IDD is then optionally interrogated to determine if any related entities have been modified since last migration to the specified target system.

Entities, which are examined in this process, fall into four general classes:

• Entities with CCDB change activity according to the selection criteria. These entities are migrated to the target system.
• Entities related to changed entities, which are unconditionally migrated with the changed entity.
• Entities related to changed entities which are migrated only if modified in the source system since its last migration to the target, even though the modification occurred outside of the CCDB selection criteria (another Management Group, CCID, userid, time range, or Status).
• Related entities, which should have been modified in the source system based on the modification of a subordinate entity, but were not. For example, if a map was modified but its related Dialog was not regenerated, that dialog would fall into this category. These entities are listed on an exception report for investigation.

Three different strategies can be employed to select IDD entities related to those that were logged in the CCDB. These strategies are specified as part of the input command file to program NDVRDSEL.
