# Deregister SAP application
<a name="deregister-sap-application"></a>

The following steps will guide you through deregistration your SAP HANA application or of your single node setup of SAP ABAP application registered with Systems Manager for SAP.

If a database has not been previously registered with AWS Systems Manager, the deregistration process will result in a `ValidationException`.

## Step 1: Get ApplicationId of your SAP application
<a name="step1-deregister-application"></a>

 **Command template** 

```
aws ssm-sap list-applications --region <REGION_ID>
```

Note the `ApplicationId` of your registration.

## Step 2: Deregister SAP application
<a name="step2-deregister-application"></a>

You can use the AWS CLI command [deregister-application](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/ssm-sap/deregister-application.html) (API [DeregisterApplication](https://docs.aws.amazon.com/ssmsap/latest/APIReference/API_DeregisterApplication.html)) to deregister your SAP application.

 **Command template** 

```
aws ssm-sap deregister-application --application-id <APPLICATION_ID> --region <REGION>
```

The parameter `application-id` is required. As the value, use the ApplicationID retrieved in Step 1.

## Step 3: Verify deregistration
<a name="step3-deregister-application"></a>

Run the command [list-applications](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/ssm-sap/list-applications.html) ([ListApplications](https://docs.aws.amazon.com/ssmsap/latest/APIReference/API_ListApplications.html) API) to verify your application is not present.
