As a permanent workaround, perform the following steps to increase the field length in the database:
1. Stop the services for ALL the CA products that connect to the mdb database.
2. Update the field length on the audit_nr_pr_id column with this command:
ALTER TABLE aud_usp_owned_resource ALTER COLUMN audit_nr_pr_id nvarchar(255)
3. Perform an IISRESET on both the APM application and APM web servers.
4. Restart the Service Desk and the APM services.
ITAM engineering will update the mdb schema in the future to change the field length on the audit_nr_pr_id column so it equals the pri_nx_desc field length.
