Connect with Salesforce
At times, you may find that you need to connect one or more of your
organization's on-premise systems with a SaaS application such as
Salesforce. Ideally, these independent systems would talk to each other
and share data to enable automation of end-to-end business processes.
Use Mule applications to facilitate communication between your on-prem
system(s) and Salesforce. (Though this use case does not extend as far,
you can also use Mule to facilitate communication between SaaS
providers.)

DataWeave and FlowRefLookup
Beyond transforming and mapping data from one format to another, you
can use an Anypoint DataWeave Transformer to access other flows in a
Mule application to acquire additional information. Use a flow lookup to
acquire information outside the message, then append it to the payload.

Steps
Log in to your Salesforce account, then navigate to the Setup tab. Now
click on Customize -> Accounts -> Fieldsunder the Build section on the
left side of the page.
Now click on New under the Account Custom Fields & Relationships
section.
In Step 1 of the new field process, select Text, then click Next to continue.
In Step 2, enter values for your new field as per the table below, then
click Next to continue.
In Step 4, check the Account Layout box, then click Save.
Your new field name appears followed by a double-underscore and a
lowercase "c": Region__c This is the new field to which DataWeave will
map the region data it acquires from another flow.

Steps
Open the Example project in Anypoint Studio from Anypoint Exchange. Do
not run the application.
Log in to your Salesforce account. From your account menu (your account
is labeled with your name), select Setup.
In the left navigation bar, under the Personal Setup heading, click to
expand the My Personal Information folder.
Click Reset My Security Token. Salesforce resets the token and emails
you the new one.
Access the email that Salesforce sent and copy the new token onto your
local clipboard.
In your SaaS Integration application in Mule Studio, click the Global
Elements tab.
Double-click the Salesforce global element to open its Global Element
Properties panel. In the Security Token field, paste the new Salesforce
token you copied from the email. Alternatively, configure the global element
in the XML Editor.
Change the contents of the Username and Password fields to your
account-specific values, then click OK to save your changes.

CreateNewSalesforceAccountFlow
The File Endpoint polls the input folder for new files every ten seconds.
When it spots a new file, it reads it and passes the content to the Anypoint
DataWeave transformer. This transformer not only converts the format of
the data from CSV to a collection, it automatically maps the input fields
from the CSV file – company_name, company_address, etc. – to output
fields that Salesforce uses in a collection.
The DataWeave also utilizes a flow lookup. Flow lookup accesses another
flow in the application to acquire the sales region for each new account.
DataWeave invokes the LookupSalesRegionFlow which uses the
company_state data to determine into which sales region the account falls.
DataWeave then maps this newly acquired data to the custom field in
Salesforce, Region__c.

LookupSalesRegionFlow
This flow consists of a Groovy component and a Logger. The script in the
component uses state information in the message payload to calculate the
sales region to which the account belongs. Invoked by the flow lookup in
DataWeave, this flow exists only to determine a sales region for each
account in the CSV file.
