# Adding warning and failure messages to validation results

You use the `CdmPolicyUtil` script include to add warning and failure messages to validation results in the CDM Policy Validation Results table. CDM expects validation warnings and failures to contain a node path, a snapshot ID, and a reference to the impacted node.

**Important:** DevOps Config is now deprecated and no longer supported or available for new activation.

## CdmPolicyUtil

-   `CdmPolicyUtil` is a public script include.
-   Because `CdmPolicyUtil` is a global script include, you do not need to invoke it like a new CdmPolicyUtil\(\).
-   You can invoke `CdmPolicyUtil` in all scopes, but the expected invocation scope is PaCE \(specifically, during the execution of PaCE policies\).
-   The proper call is `CdmPolicyUtil.methodName(parameters)`.

**Note:** If you add warning and failure messages to validation results manually instead of using CdmPolicyUtil, the snapshot validation status will show Execution Error.

## Methods

-   **addFailure**

    Adds a failure message. The message appears on the **Validation results** tab for the snapshot.

    Parameters:

    -   **Output**: Policy decision for the subject snapshot \(**primarySnapshotId**\).
    -   **cdmNode**: Node \(**sn\_cdm\_node**\) that caused the failure.
    -   **name**: Name of the failure.
    -   **description**: Description of the failure.
-   **addWarning**

    Adds a policy warning message. The message appears on the **Validation results** tab for the snapshot.

    Parameters:

    -   **Output**: Policy decision for the subject snapshot \(**primarySnapshotId**\).
    -   **cdmNode**: Node \(**sn\_cdm\_node**\) that caused the warning.
    -   **name**: Name of the warning.
    -   **description**: Description of the warning.
-   **getLastCreatedSnapshotIds**

    Returns the latest created and published snapshot IDs for the supplied **additionalDeployables**. If no published snapshot is available for a particular deployable, adds a debug message.

    Parameter:

    **additionalDeployables** – can be passed directly as it comes to the policy.

-   **getLastPublishedSnapshotIds**

    Retrieves the latest and published snapshot IDs for the supplied **additionalDeployables**. If no published snapshot is available for a particular deployable, adds a debug message.

    Parameter:

    **additionalDeployables** - can be passed directly as it comes to the policy.
