have you created methods without implementing them in the class. and you want them to implement in program...

or you have implemented the methods and you want to use the class in your program...

First declare a reference object in the program for that class type

say for example you have created a class cl_test

now declare the object...

data : w_obj type ref to cl_test.

now press ctrl+F6 from keyboard and select the second radio button (ABAP Object Pattern ) then hit enter...

now select the second radio button create object,

and in the instance type w_obj and for class type cl_test and then hit enter.

this will create object for the class you have created and then you can call methods or use attributes of that class in your program using this object.....

to call a method do the following

press ctrl+F6 and then select second radio button and then select the first radio button call method and in instance give w_obj and for class give cl_test and give the method name you want to call....

and then hit enter...

to uxse any attribute you can do it this way....

w_obj->attrib1.

Hope this is helpful...

Regards,

Siddarth
