Defining and Creating a Genil Model :
You could define and implement dynamic models using IF_GENIL_APPL_MODEL Interface.
use GENIL_MODEL_EDITOR OR GENIL_MODEL_BROWSER to create static models ,
As Genil component class extends default implementation of IF_GENIL_APPLMODEL_PERSISTENCY namely CL_WCF_GENIL_ABSTR_COMPONENT.
Step 1 : Go to Transaction SE24 or SE80 ,Create a new abap Custom Genil Class
ZCL_CUSTOMER_MODEL
As this class use statically defined model we inherit from CL_WCF_GENIL_ABSTR_COMPONENT.
Save and activate the class.
Step 2: Registering of Genil component is done using Transaction SM34 ,
Enter View Cluster name as CRMVC_GIL_APPDEF or we can use maintaince view CRMV_GIL_COMP
Click maintain button.
Maintain the entries for Component Definition , Component Set Definition and Component Assignment.
Step 3: Create a new Master Table name as ZMAST_CUST using transaction SE11.
Creating a Genil Business Objects.
Key Structure of Customer Data.
Attribute structure of a Customer Data
Table Type of Attribute Structure.
Create a Lock object of master table ZMAST_CUST.
Step 4 : Go to Transaction GENIL_MODEL_BROWSER,
Give component name as ZCUST .
- a.) Click on Change button and Right Click on Root Objects -> Give Object Name as Customer
Add Key Structure Name , Attribute structure name and Create structure name .
And check web service enabled.
Keep Attribute Structure Property -in Changeable mode , So that while creating a object you can see a list of fields in Change mode in Object Browser .
Step 5 : Open a custom genil class ZCL_CUSTOMER_MODEL and redefine all this metohods as shown below.
Create a new custom class name as ZCL_CUSTOMER_API which will to hold the API methods to retrieve data from database.
Declare GT_CUSTOMER as a global attributes ZATTR_CUST_TAB ( Attribute Structure of Customer ) of ZCL_CUSTOMER_API

Coding Part is Done to create genil implementation class.
STEP 6 : go to transaction genil_bol_browser -> Click on Create a New Root Object
Select the root object as Customer double click it.
Enter the parameters value Custno -
you can add you own custom logic to default set the value of the attributes
Click on Create Object
Here Guid and Custno is in display mode , while remaining atrributes are in changeable mode - Enter the values of the Attributes.
Click on Save Button.
and Check the database table ZMAST_CUST.
In my next blog ' http://scn.sap.com/community/crm/webclient-ui-framework/blog/2012/09/25/implementation-of-a-custom-g... ' will use this Custom GenIL component set to create a New custom component with create and save the data
in database
