give definition Name : ZBADI_CUST--> Press F5 button for Creating the Definition.
Give Description for the BADi Definition : XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
In the Attributes tab you will find "TYPE" Tab
there you will check the Check Box as "Multiple" because this badi definition is active for multiple BADI Implementations
save & check the Badi Definition.
Click on "Interface" tab
Double Click on the Interface Name that is "ZIF_EX_BADI_CUST"
here the screen is take you to tcode SE24
here you will declare the methods
