Creating New Method

Former Member — Tue, 25 Nov 2008 14:02:49 GMT

Hi,

I am creating a new method METHOD2 in an existing class.

I am using an internal table which is populated in other method METHOD1.

But when I tried to call the METHOD2 in main program,it is saying that METHOD2 is not defined.while I have activated the method.

it is to be noted that I have not given any exporting,importing,changing parameter to this method.Do I need to give it compulsarily>if yes,then can I give the internal table as changing parameter,the one which is being populated in METHOD1.?

Thanks in advance!!

No, it doesn't need to define an interface in a method, but check in which section you've defined the method2: it has to be in PUBLIC SECTION

DATA:

Object references

o_bluecollar_employee1 TYPE REF TO lcl_bluecollar_employee,

Create bluecollar employee obeject

CREATE OBJECT o_bluecollar_employee1

EXPORTING im_no = 1

im_name = 'Gylle Karen'

Display employee list and number of employees. Note that the result

will be the same when called from o_whitecollar_employee1 or

o_bluecolarcollar_employee1, because the methods are defined

as static (CLASS-METHODS)
