Audit management master data sync fails during bulk import with duplicate key errors

[hanstechie]

We’re experiencing critical failures when bulk importing audit master data into TrackWise 9.0. The import process consistently fails halfway through with duplicate key constraint violations, even though we’ve validated the source data for uniqueness before upload.

The error occurs specifically when syncing audit templates and associated master data records:

ERROR: Duplicate key violation on AUDIT_MASTER_DATA
Constraint: UK_AUDIT_TEMPLATE_ID violated
Failed records: 247 of 850

Our bulk import handles around 850 audit master records, and we’re seeing failures at the 600-record mark consistently. The audit log reconciliation shows discrepancies between what was imported and what’s reflected in the system. We need to understand proper error handling for bulk imports and ensure master data key uniqueness is maintained throughout the process. Has anyone dealt with similar duplicate key issues during large-scale audit data migrations?

Two-phase is definitely the right direction, but you need more granular control. Here’s what worked for us when we migrated 2000+ audit records:

First, implement proper bulk import error handling with these steps:

// Pseudocode - Bulk import with duplicate detection:
1. Query existing AUDIT_MASTER_DATA keys into HashSet
2. Filter import dataset: exclude records where key exists in HashSet
3. Batch remaining records into groups of 150 (optimal for TW 9.0)
4. For each batch: wrap in try-catch, log failures to separate table
5. Commit successful batches, collect failed records for manual review
// Reference: TrackWise Data Management Guide Section 7.3

For master data key uniqueness, the UK_AUDIT_TEMPLATE_ID constraint is enforced at database level, so you MUST validate before insert. Your source data validation isn’t enough - you need runtime validation against the live database state because other processes might be creating records concurrently.

For audit log reconciliation, implement a post-import verification process:

SELECT template_id, COUNT(*)
FROM AUDIT_MASTER_DATA
WHERE created_date >= [import_start_time]
GROUP BY template_id
HAVING COUNT(*) > 1

This query identifies any duplicate template IDs that slipped through. The reconciliation should compare your import manifest (what you intended to import) against what actually exists in the database after import completion. Create a reconciliation report that shows: records attempted, records succeeded, records failed with reasons, and records that need manual intervention.

Key architectural points: Use pessimistic locking if multiple import processes run concurrently. Implement idempotency by checking record existence before every insert operation. Set your transaction batch size to 150 records max - this is the sweet spot for TrackWise 9.0 performance without causing memory issues. Enable detailed audit logging for the import process itself so you can trace exactly which records failed and why.

The 600-record failure point you’re seeing is almost certainly a transaction boundary. TrackWise’s default transaction batch size in 9.0 is 500-600 records, so when it hits the first duplicate in that batch, the entire batch rolls back. Smaller batches will give you better error isolation and allow partial success rather than all-or-nothing failures.

Looking at your error message, the UK_AUDIT_TEMPLATE_ID constraint suggests you’re trying to import audit master data records that reference the same template ID multiple times. In TrackWise’s data model, each audit template can only have one master data configuration record. If your source data has multiple rows with the same template ID, you need to consolidate them before import. Check if you’re accidentally duplicating template references during your ETL process. The 247 failed records out of 850 is roughly 29%, which might indicate a systematic issue with how template IDs are being generated or mapped from your source system.

The audit log reconciliation discrepancy you mentioned is a red flag. This typically happens when the import process doesn’t properly log failed records versus successfully committed records. In TrackWise 9.0, the bulk import mechanism should be writing to the audit trail for each record attempt, but if transactions are rolling back, those audit entries might be getting lost too. You need to implement a pre-validation step that queries existing AUDIT_MASTER_DATA records and filters them out before attempting the bulk insert. Also consider breaking your 850 records into smaller batches of 100-200 to isolate where duplicates are actually occurring.

We had similar issues last year. The problem was that our audit templates had dependencies on other master data tables that weren’t being imported in the correct sequence. TrackWise enforces referential integrity strictly, so if you’re importing audit master data before the related lookup tables are populated, you’ll get constraint violations. Check your import order and make sure parent records exist before child records. Also, the 600-record mark failure suggests a transaction batch size issue - TrackWise might be committing in batches of 600 and rolling back when it hits the first duplicate.

Thanks for the insights everyone. We’re using a custom import script, not the standard utility. I think the issue is a combination of what you’ve all mentioned - we’re not checking for existing records AND our batch size might be too large. Would it make sense to implement a two-phase approach: first query for existing keys, then only import net-new records?
