Best Practices for CDK Dealers Switching to Dirty Core Tracking
- Setup Actions
- PartsRec Support
- Enable “DMS Dirty Core Tracking” in Company Admin. Set Flag to “True”.

- Verify that the Beginning Inventory shows cores.

- Confirm that DC transactions are visible in the Outstanding Dirty Core tab.

- Enable “DMS Dirty Core Tracking” in Company Admin. Set Flag to “True”.

- Conduct a physical count of dirty cores.
- Update core counts in DMS using CMOD or CMNT.
- CMOD and CMNT transactions will appear the next day in the Outstanding Dirty Cores tab in PartsRec. You will want to create a memo for accounting to post the adjustment to your parts inventory to account for dirty cores on hand.
- Document cores sent back but not yet credited.
- Send a list of “cores in transit” to PR Support.
- PartsRec Support
- Cleanup Actions

- Matching Going Forward
- Parts Department
- Matching to invoices - No change here. You will receive in the part as normal and match the transaction to the debit invoice.

- Matching to credit invoices – Matching transaction will be program code VRTN / transaction code DC. If you do not have an available match, check to make sure core was removed from inventory and sent back for credit in CDK’s DC tracking program.

- Matching to invoices - No change here. You will receive in the part as normal and match the transaction to the debit invoice.

- Troubleshooting Notes
- A missing core transaction could mean they did not follow the process properly. Remember, these are now like a normal received/return transaction.
- There will not be a pad error unless another issue has occurred.
- VRTN DC = Vendor dirty core. CMOD DC or CMNT DC is a plus/minus adjustment for the core.
- There is a VRTN report in CDK just like the MSR report.
