OSB 12C - Unable to deploy service using File Transport

When i was trying to deploying a OSB project  with business service having File Transport from JDeveloper to OSB cluster, deployment failed due this error

Service Bus Deployment Error
No transport provider registered with ID: file

After going through Oracle documentation, i found out that File Transport was only  targeted to  my OSB cluster. It should targeted to both the Admin and OSB cluster.

 Solution:

Follow these steps:

 - Login into WLS Admin console and edit a session

- Go to Deployments

- Select File Transport application "Service Bus File Transport Provider"

- Open "targets"

- Select change target option and add target to both "Admin & OSB Cluster" for OSB Cluster domain. For single server domain (just admin server), target will be just "AdminServer"

- Save and active changes.
