Bettina Lieske explained in her blog entry how to find a special service in the Enterprise Service Workplace. I would now like to use the ES Workplace as starting point to build a composite with the Visual Composer.
First of all I search for the services I would like to use in my application. In this case I need the service operations “Find Customer Address Basic Data by Name and Address” and “Find Customer by name and Address”. In the ES Workplace you get all the information about the Service – you can even drill down to the WSDL file.
The idea behind this simple composite is to search for a patient (customer) by name or place of residence, and get detailed address information in return. Now, I look for these services in the Visual Composer service repository under “ERP Foundation” and “Business Partner Data Management”, and put them into the Visual Composer. In the end the model for the application looks like this:
I build an input form with two search criteria and submit this information to the service. The result from the service I would like to display in a table. By selecting a line from that table I submit the “ID” into the next service and show the detailed information in a second table.
Yes, I know this is not a very big and powerful application but it shows how easy it is to use a service directly from ES Workplace and very easily build an application based on it. Furthermore, it shows you the new look and feel from the latest Visual Composer version in the Composition Environment. If you need more information about Visual Composer I’m sure you will find it here: http://www.sdn.sap.com/irj/sdn/nw-vc
Please make use of the ES Workplace and the Visual Composer. I’d be very keen to hear about your experience and your feedback.
