Platform Notice: Cloud Only - This article only applies to Atlassian apps on the cloud platform.

Summary

When you import multiple asset objects with the same object references, only one object retains its references. The other objects are imported without references. In the import history, you may see the following error: “Concurrent modification on attribute.”

Diagnosis

Replicating the problem

  1. Create a CSV File to Import multiple new objects with the same Object Reference.

  2. Import CSV into Assets using the steps: Prepare your data for importing into Assets

  3. After Importing data > Expand Import History and observe the error: Concurrent modification on attribute

Cause

This happens when the Attribute that has a Referenced Object has a Unique value selected.

Solution

  1. Either remove the Unique checkbox from the attribute settings that reference the object

  2. or CSV file should have unique referenced objects.

To remove the Unique value from the attribute

  1. Navigate to the destination Object Type where Import is performed > For referenced attribute > Click on 3 dots (•••).

  2. Click Configure > Under General > Uncheck Unique parameter > Update.

  3. Once done, perform the Imports again.
