DataServer
Physical Schema(Schema)

Logical Architecture
Technology-File
Logical Schema(LG_File_SRC)
Technology-Oracle
Logical Schema(LG_ORCL_TRG)
Context
Global
Schema Tab - LG_File_SRC - Physical Schema of File
    LG_ORCL_TRG - Physical Schema of Oracle)

Steps:
1.Login to ODI
2.Go to Designer Navigator
3.Expand Model Accordion
4.Create Model for Source
FILE_SRC(Model)-->Logical Schema as mentioned above (i.e., LG_File_SRC) --> Reverse Engineer tab, select context as global)
Right click model and click on new datastore
Provide DataStore name as "Header" --> Resource Name "Select File Name"
Go to File tab --> File Format as "Delimited" --> Field Seperator (others --> ,)
Go to Attributes tab --> Create attributes as mention below screenshot

Provide DataStore name as "Detail" --> Resource Name "Select File Name"
