How do I prevent enumeration imports from causing data loss?

To prevent enumeration imports from causing data loss, you can create a Case with SAP Ariba Customer Support to request a change to the Application.Base.VerifyUnchangedEnumerationValues parameter.

Sometimes new enumerations will cause data loss by replacing existing enumerations. By enabling this parameter, your site provides a warning if an enumeration import will break referential integrity.

When managing enumerations, removing an existing enumeration might cause data loss. For example:

• Value objects that use the enumeration no longer show the display value.
• For objects that have not yet been published, the value selection is removed without notice upon saving.
• Updates to objects remove the value selection without notice upon saving.
• If you add the same value again with a different display value, existing objects showed the new display value without notice.
