LANSA Composer
The solution automates updating customer data in an
ERP application running on an IBM i server with data
from a web application.
Customers maintain their data using the customer
information web application.
LANSA Composer accepts data from the web
application, reformats the data, and enters the data
into the ERP application automatically.

Current situation describes the existing processes and highlights
inefficiencies, manual processes and cost concerns.
Current situation
The requirements define the processes the company would like to
automate and where to enhance existing processes.
Requirements
The solution describes how LANSA Composer can be used to implement the
requirements including automating the processes.
Solution
The benefits highlight measurable outcomes, e.g. process efficiency and
reduced costs, derived from implementing the solution design.
Benefits
This use case is based on a customer experience using LANSA Composer to implement an
automated solution that achieved tangible outcomes.

Current situation
ACME Corporation operates an ERP application, which was purchased as a software package.
The ERP system is a 5250 legacy application that runs on an IBM i server.
ACME receives advice of changes to customer data by email, paper mail, or phone calls.
Customer service staff at ACME transcribe data in emails, paper mail, or phone call notes to
update customer data using the customer module of the legacy application.
Updating customer data is a manual process and prone to error, e.g. transcription errors occur
when customer service staff enter the data. Transcription errors in addresses cause deliveries
to incorrect addresses and fixing the problem makes deliveries more expensive. The data in
email and paper mail documents is often incomplete, e.g. no zip code. Correcting the
incomplete data adds to the time required to process the updates.

Requirements
The requirements are:
1. A self-service web application where customers manage their customer data.
2. Automate updating customer data in the ERP application.
The self-service web application for managing customer data will be a new application and
separate from the legacy ERP application.
LANSA Composer will accept customer data from the self-service web application, and update
the customer data in the ERP application automatically, using the terminal service to operate
the ERP application programmatically. The terminal service imitates a person typing data using
a keyboard.

Solution: update customer data
2. The self-service web
application sends the
customer data to
LANSA Composer.
1. Customers use the self-service
web application to maintain
their customer data.
3. LANSA Composer reformats the
customer data into a stream of key
strokes, and uses the terminal service
to imitate a human operator updating
customer data in the ERP application.

Solution: customer data update processing steps
A business analyst builds the
script that LANSA Composer
uses to automatically
perform the steps required to
receive the customer data,
reformat the data for
updating the legacy
application, and send a
stream of keystrokes to the
ERP application.

Benefits realised from the automated solution
• The self-service web application reduced the customer service workload by eliminating
administrative time required to fix incorrect or missing customer data
• Updated customer data is more accurate, and available as soon as customers save the
changed data
• More mailed items reach the correct address thereby reducing returns and re-mailing costs
• Fewer incorrect delivery addresses reduced courier costs
LANSA Composer provides business process integration (BPI) tools used
by business analysts to automate and integrate business processes.
It is a simple, and cost-effective way to get business transactions in and
out of your business systems with less human effort.
