Calling a method to a program

Question

hello,
I have a requirement that I am working on, I need to create a program that will have vendor number and vendor bank account number on the selection screen.
Now what I need to do is I need to call a method from a class that will do some kind of validation, method name is  'validation'
My problem here is that method validation has only vendor bank account number as a parameter. Vendor number is defined as an attribute in the class, let's say z_vendor, and in the method we are using Z_vendor as a vendor number.
Can you please tell me how can I set the value of the attribute to the one that the user will enter using a FM and then how to call the method validation in to my program.
I can not make any change the way class has been declared.
The attribute z_vendor is defined as follows:
1. Level - Instance Attribute
2. Visibility - Public
I am very new to OOPS.. so any help will be really appreciated.

Hi Rahul,
You can do like this:
data:lr_object type ref to CLASS (NAME of your class)
create object lr.
1.lr_object->z_vendor = vendor no.
2. call method lr_object->method name (in Importing parameter pass the vendor bank account no.
And then in the method your vendor no and bank account will be passed.
Thanks
