When a contract is created by copying an existing one, the CVR model from the original contract can carry through into any CVR that is generated. Changing the CVR model on the contract afterwards does not update a CVR that has already been created — the existing CVR keeps the model it was built with. This article explains how to fix this by deleting the incorrect CVR and creating a new one.
Why the CVR model does not update automatically
The CVR model set on the contract record controls which template future CVRs use. However, a CVR that has already been generated is effectively 'locked' to the model it was created with. The following actions will not update an existing CVR's model:
Changing the CVR model on the contract and saving.
Closing and re-opening the CVR.
Restarting COINS processes.
The only way to apply the correct model is to delete the existing CVR and create a new one after the contract model has been corrected.
Correct the CVR model on the contract
Before deleting the CVR, make sure the correct model is set at contract level.
Open the contract record.
Go to the CVR model drop-down and select the correct CVR model.
Click Save.
Delete the incorrect CVR
You can delete an individual CVR directly from the CVR Workbench screen.
Go to CVR > CVR Workbench.
Open the contract.
Select the CVR with the incorrect model.
Click Delete.
⚠️ Important: The Delete button is available on the CVR Workbench screen at contract level. If you do not see a Delete option, check you are viewing the CVR list under the contract rather than a summary or enquiry screen.
Create a new CVR
Once the incorrect CVR has been deleted and the correct model is saved on the contract, create a new CVR from the CVR Workbench. The new CVR will use the model now set on the contract.
📌Note: You cannot create a new CVR with the same number as an existing one. Deleting the original CVR first frees up that CVR number.
Using Purge CVRs for bulk deletion
The Purge CVRs function (CVR > Administration > Purge CVRs) is designed for bulk removal of CVR data across a range of periods — for example, clearing historical data to reduce database size. It is not the recommended approach for fixing a single CVR with the wrong model. Use the Delete button on the CVR Workbench instead.
If you do need to use Purge CVRs, note the following restrictions:
Completed CVRs cannot be purged if they are required for CVR (BPF) enquiries and reports.
The 'To' period cannot be later than the last period of the previous financial year.
Run in Check mode first to see what would be deleted before running in Delete mode.
