Step 6 - Add a Business Data Library

In this step you are going to add more business data by creating a business data library to the flow by importing it.

Up to now you have been using a Customer Credit Transfer Request (i.e. Pacs008) in the flow. There is a lot of data in a Pacs008, much of it unused in the payment flow. If you like, you can break down the Pacs008 into smaller elements, and one way of doing this is by using an aggregate function within the flow to split the Pacs008 as soon as the flow is initiated.

You will need to import the message components and message elements that you will want to add.

You will also add some business data to a response and propagate that in the payment flow as well. This will be a reservation reference supplied by the debtor agent’s accounting system in response to a validation request.

First, create a business data library to store the new business data. Start by selecting the flow node in the explorer and then right click and select "New>v2Flo>Business Data Library"

Enter a name and a description for your business data library. Let’s give it a name of "Outbound Payment Flow Business Data Library" and a description of "This library contains all the business data elements for an outbound payment for the tutorial".

When you have finished it should look like this:

All the data you need for this flow is contained within the Pacs008 and you could simply use the entire Pacs008 throughout the flow. However, in real life, you will make calls out to other systems using a subset of the data contained in the Pacs008. Although at this stage you do not know how the flow is going to develop, lets add in some further business data that are commonly used in a request to an accounting system. By defining this data as separate to the Pacs008, it will be easier to see in the flow what data is used for different requests.

Open up the Outbound Payment Business Data Library and then add following business data elements:

You will not see the ISO Data Types that want immediately, you will need to Import them first by:

Once updated the Business Data Library should look like this

IPF comes with a data model that has a Message Data Structure -the message(s) that are used to initiate a flow and a Processing Data Structure - the data this subsequently received from external domains (see later) or generated that is used in the flow. You will also see a category of 'Additional Identifier' which would be used if the data is a client-specific identifier that you you wanted to be able to search on using the IPF Operational Dashboard or your own GUI.

Since this data is already contained in the message that initiates the flow we won’t assign it a data category.

You will update the use case so that, when an account validation request is received by the debtor agent’s accounting system, it will automatically reserve funds, update the intra-day balance and provide a reservation reference in response.

You will use that reservation reference later, so lets also add that to the Business Data Library.

You have used a mapping function definition before (for the Pacs002 used in the notification). In your use case you will be breaking up the Pacs008 upon initiation of the flow so that you can use those data elements in subsequent calls.

From the Flow:

Your function definition should look like this:

And now you need to call the function from the Initiation Behaviour so that the data is available when the flow is initiated.

You have chosen not to use 'Perform Enrichment' as there is no need to persist the data. Its already available in the Customer Credit Transfer, and you are splitting it to make the data in the flow more explicit - there’s no 'new' data that needs storing.

You have created more business data and built another mapping function - now you need to update the flow to add this business data.
