Hi sachin,

In Interfaces (OOPS concept) you cannot validate Data. Generally Interfaces are used for Validation purpose. like if you want to validate some data in many classes, in that case you just create an interface and declare method for that validation and implement that interface in all classes where you want that validation.

hi Sachin.,

we can do validations in interfaces.

before seneding the data into SAP/ Files we need to do all validations for the data depends up on the requirement.

the validations totally depends on the req. only.

here im attaching the piece of code in which validations has been done for interface.

go through it for better understanding.
