When designing a data model, you can now see the following impact analysis on data model changes:

  • If you change an optional simple type element to a mandatory one without a default value and null values exist for the given element, or change an optional complex type element to a mandatory one, or change the maximum occurrence of an element from 1 to n or vice versa, it will be considered as a high impact level change when you deploy the modified data model to the MDM server.

  • If you remove a mandatory simple type element, it will be considered as a medium impact level change when you deploy the modified data model to the MDM server.

  • If you change an optional simple type element to a mandatory one and no null values exist for the given element, or change a mandatory element to an optional one, or change an optional multi-occurrence element to a mandatory multi-occurrence one or vice versa, it will be considered as a low impact level change when you deploy the modified data model to the MDM server.
