10 Select the Overridable in Blueprint check box to allow users such as an application architect to
override the value for the property in an application blueprint.
If the property type is Computed, the Overridable in Blueprint check box is not applicable.
If a property is not overridable in the blueprint, you cannot set the Auto-Bind type to Consume.
For example, the application catalog administrator might configure the vFabric tc Server service to
have a JVM heap size of 512MB. But for large deployments, the application architect might change
the setting to 1024MB.

What to do next
Specifying external service definitions has no impact on deployments unless you create an external
service instance in a deployment environment to enable the external service definitions on all of the
deployments under the deployment environment. See Map an External Service Instance.
Create provider specification for the custom external service version. See Create Provider Specification
for an Advanced External Service Version.
Create Provider Specification for an Advanced External Service
Version
An advanced external service requires you to create a provider specification. This specification is a set of
one or more scripts that defines how an external service can be configured, updated, rolled back, and
torn down in various service provider environments such as VMware Data Director or Amazon RDS. The
provider specification also has properties that you can define to connect to the provider and the provider
specific parameters.
You can view examples about how to create a provider specification for an external service from the
Library > External Services page.
You can change only the group membership settings for the external service. The new membership
settings are then propagated to the service provider specifications of the external service.
User cannot update group membership of the service provider spec separately.
