Description

Background
Existing version of Import API allows for importing types that are not already present in the system being imported in. This causes import to fail in the cases where the data being imported happens to have the additional attribute.

Solution
During import, existing types are checked to determine if the types being imported have additional attributes. If additional attributes exist, then the existing type is updated with the new attributes. The import then proceeds.

Impact Assessment

• Import API:
  • Type import: Additional capability (mentioned above).
  • Entity creation and processing: No impact.
• Export API: No impact.
