3. change directory into `first-network` sample

cd first-network
cd first-network

4. Next, start the BYFN network - additional flags (to the `byfn.sh` script below) must be specified, as we're using CouchDB as the world state database (different to that specified on the Fabric BYFN page) - we also want to start a Certificate Authority (CA) for **each** organization.

5. Execute the following commands in sequence from the `first-network` directory:

./byfn.sh -m generate

./byfn.sh -m up -s couchdb -a
./byfn.sh -m generate
./byfn.sh -m up -s couchdb -a

If the command works successfully, the first command will generate Fabric network / security artifacts(see this [link](http://hyperledger-fabric.readthedocs.io/en/release/build_network.html#generate-network-artifacts for more info). Following the second command (above), the BYFN network is started, and verify that you see the following output before proceeding:

# Invoking a {{site.data.conrefs.composer_full}} business network from another business network
{{site.data.conrefs.composer_full}} includes functionality that can be used by a business network to access an asset, participant, or transaction that is recorded in another business network.

This tutorial will demonstrate the steps that a business network developer needs to take in order to invoke a {{site.data.conrefs.composer_full}} business network from a different business network. As part of the tutorial you will deploy the same business network twice. The business networks can be on the same channel or different channels. The business network used in this example will be the tutorial network that is outlined in the [developer tutorial](./developer-tutorial.html). This tutorial will refer to the business networks as "A" and "B"

./createPeerAdminCard.sh

## Step Two: Create a second channel (Optional)
## Step Two: Define the business networks
1. Follow steps one and two in the [developer tutorial](./developer-tutorial.html). This will be network A.

The simple network config used in the previous step only creates one channel by default. If business network B is to be deployed to a different channel, then the channel should be created now by using the Hyperledger Fabric operational tools.
2. Follow steps one and two again but create a business network called `other-tutorial-network`. This will be network B.

After the channel has been created a business network card needs to be created to deploy to this channel.

1. Create a connection profile that specifies the second channel

2. To create the business network card run the following commands.

export PRIVATE_KEY=~/fabric-tools/composer/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/msp/keystore/114aab0e76bf0c78308f89efc4b8c9423e31568da0c340ca187a9b17aa9a4457_sk
export CERT=~/fabric-tools/composer/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/msp/signcerts/[email protected]
composer card create -p <Path to profile> -u PeerAdmin -c ${CERT} -k ${PRIVATE_KEY} -r PeerAdmin -r ChannelAdmin --file [email protected]
composer card import -f [email protected] -n otherPeerAdmin@hlfv1

## Step Three: Define the business networks
1. Follow steps one and two in the [developer tutorial](./developer-tutorial.html). If business network A and business network B are being deployed to the same channel then a second business network will need to be created with a different name but with the same model, script and ACL files. This tutorial will assume this will be called `other-tutorial-network`.

2. The transaction logic needs to be updated to query an asset in business network B and then update the quantity property of an asset in business network A.
3. The transaction logic needs to be updated in network A and to query an asset in business network B and then update the quantity property of an asset in business network A.

Replace the contents of the `logic.js` script file to update the transaction processor function to be the following. Where \<CHANNEL\> needs to be replaced with either the name of the channel created in step two, or `composerchannel` if the business networks are on the same channel; and where \<BUSINESS NEWORK NAME\> is either `tutorial-network` if the networks are on different channels, or `other-tutorial-network` if the network are on the same channel.
