Read A Flat File Using File Layout And Insert Into The Specific Component Using CI ( Bulk Insert )

Read A Flat File Using File Layout And Insert Into The Specific Component Using CI:
Approach:
Get the sample flat file and create a File Layout. 
Create the CI for the component.
Create an AE and drag the File Layout and CI for dynamic code generation in the peoplecode action

Sample Code:
