You have seen how to expose FT transaction using TWS in the previous session.
What happens to Overrides? How does TWS handle them?

TWS and Hook Routines
You can customize a T24 application using Version routines.
Let us now see how Version routines work with TWS

Input Routine
Workshop 1
Create a TWS project for the Account application and test the same.
The version used, – Should contain all the mandatory fields – Should have an Input Routine that will check whether the currency is left blank and if currency is left blank, – Value USD to be to the currency field.

Arrangement Architecture – Quick Overview
T24 Arrangement Architecture (AA) is a comprehensive, component based product definition and servicing framework.
The foundation of the T24 Arrangement Architecture (AA) is the Product Builder which enables the design, proofing, and publishing of products and services to the Product Catalogue.
The published Products are used to create and control the individual customer Arrangements which are serviced by T24.
Servicing of T24 Arrangements is accomplished through Arrangement Activities.
Unlike most other T24 applications, an Arrangement Activity is first explicitly selected and any necessary input is restricted to the appropriate attributes.
Each Activity is comprised of one or more Actions which are the specific units of processing performed by a Property Class
AA Terms Product: A Product is a saleable unit made up of properties and conditions. For example: PERSONAL.LOAN. Where,
Property is an instance of product class that contains attributes and activity. Ex: ACCOUNT.
Conditions define default values and negotiable rules. Ex: PERSONAL.LOAN.
In an arrangement, negotiable properties can take input from the users while others will have conditions in default.
Activity is a Business function which is triggered by a user, the close of business, or another T24 application like Funds Transfer or Teller. Ex: LENDING-NEW-ARRANGEMENT.
How to launch an Arrangement Activity in T24
Launch a new Arrangement Activity.
Based on the product selected, key in the values like Customer number, currency or effective date to validate the eligibility of the Customer for the product.
PRODUCT and ACTIVITY get populated automatically.
When the validation is successful, T24 will automatically load the various properties of the arrangement.
Key in the negotiable values.
Submit the arrangement for authorisation.
You can also create an arrangement activity using AA.ARRANGEMENT.ACTIVITY, but you have to specify the PRODUCT and ACTIVITY manually.
How To Expose AA as TWS Web Service
Create a version for AA.ARRANGEMENT.ACTIVITY.
Why? – Because AA.ARRANGEMENT.ACTIVITY holds the arrangement
activities.
While creating the version, auto populate ACTIVITY and PRODUCT.
Why ? – Failing to supply this information will result in an error when creating web services.
Create PW.ACTIVITY and EB.SERVICE record as usual.
TWS and AA
PRODUCT and ACTIVITY fields are auto populated in the VERSION record.
Once the version is created, PW.ACTIVITY and EB.SERVICE records has to be created as usual.
Create the TWS project.
PW.ACTIVITY and EB.SERVICE records

Workshop 2
Create and test a TWS Project, using an existing AA.ARRANGEMENT.ACTIVITY Version.
