CX_SY_REF_IS_INITIAL

[Former Member]

OO Experts,

I get this error. The details are in german but translated I get "It tried with a “ZERO” object reference (points to “nothing”) a component to access (variable: “O_ZTMM_TEST_CLASS”). An object reference must point to an object (an instance of a class), before one can use it to the access to components. Either the reference was not ever set, or it was set for CLEARS with an instruction to “ZERO”.

for calling this method:

call method o_ztmm_test_class->get_checkdigit

exporting

upc_in = '000000002820011800'

importing

upc_out = lv_newupc.

Anybody know what is happening?

Did you create the object o_ztmm_test_class? Look at CREATE OBJECT....

Thanks, I am new to OO, I am forcing myself to learn.

That worked.

Glad it helped. Don't worry, you are not alone on this one. I am also trying to grasp the OO aspects.
