Error Message when Merging Cases: “Top level error: System.DmlException - Delete failed. First exception on row 0 with id 000xxxxxxxxxxxx; first error: INSUFFICIENT_ACCESS_OR_READONLY, insufficient access rights on object id: []”

When attempting to merge cases using Case Merge Premium, users may receive the following error: “Top level error: System.DmlException - Delete failed. First exception on row 0 with id 000xxxxxxxxxxxx; first error: INSUFFICIENT_ACCESS_OR_READONLY, insufficient access rights on object id: []” The user is unable to complete the merge. This is due to a lack of delete permissions for an object involved in the merge that is configured to be deleted after it is cloned to the master case.

Symptoms

When attempting to merge cases using Case Merge Premium, a user receives the following error: “Top level error: System.DmlException - Delete failed. First exception on row 0 with id 000xxxxxxxxxxxxxxx; first error: INSUFFICIENT_ACCESS_OR_READONLY, insufficient access rights on object id: []”

Solutions

Enabling the "Extend Record Access" option provides an immediate solution for future merge operations.

If enabling this setting is not an option, please review the following:

Start by checking the first 3 digits of the ID number returned in the error message: First exception on row 0 with ID 000xxxxxxxxxxxx
This 3-digit prefix identifies the Object for which the error is occurring.

Cross-reference the 3-digit entity ID with this list of Standard Object Entities with their IDs to determine the object for which the deletion is failing: http://help.salesforce.com/apex/HTViewSolution?id=000005995&language=en_US

If it's not in there, it is probably a custom object and here's how to determine which:

Take the 3-digit entity prefix, for example, a0B
While logged into your organization, modify the URL in your browser to have ...salesforce.com/a0B/e and press enter.
This will bring up the new/edit screen for the object in question.

Next, ensure that you have given the affected user sufficient permissions to the object that you wish to delete upon merging cases; permissions can be assigned via profile or permission set.

For example, if Delete Original for Attachments is enabled, which is common, the user performing the merge will need either to own all of the cases they are merging, have delete permissions on Case and Attachments or Files (depending on what's being used in the Org), or Modify All Data org-wide. https://help.salesforce.com/HTViewHelpDoc?id=notes_del.htm

(It is also important to check your Case Merge Premium Settings to verify that you actually want to delete this specified child object from the duplicate case(s) upon merging.)

Status

This is a change in behavior mandated for Salesforce's security team.

Case Merge Premium 2.81 and later allows administrators to opt to "Extend Record Access" in the context of the merge.

Additional Information

If you are still receiving the error after confirming the proper object permissions for the affected user and/or configuring the "Extend Record Access" setting, contact Vicasso for support: support@vicasso.com
