Syntax Error: Result Type of function method cannot be converted

[Former Member]

Perform stmt: PERFORM get_delta_position_increases USING l_p_accumulator

CHANGING l_wrk_position.

Subroutine:

FORM get_delta_position_increases

USING i_p_accumulator TYPE REF TO cl_accumulator_trg

CHANGING c_wrk_rep_position TYPE trls_rep_position.

DATA: l_p_accumulator TYPE REF TO cl_accumulator_trg,

• Get Clone of Accmumulator

l_p_accumulator = i_p_accumulator->get_clone( ). --> Syntax error pointing here

CALL METHOD l_p_accumulator->reset_values( ).

ENDFORM.

Syntax error I am getting:

Result Type of function method cannot be converted into the type of l_p_accumulator.

Any pointers please.

Thanks,

what is the type of the returning parameter in method iget_clone( ) from class cl_accumulator_trg?

[Former Member]

RE_CLONE type ref to IF_ACCUMULATOR_TRG.

Well, that's why. It's returning an interface, not a class.

I don't have your class in my system, but most likely the interface implements that class

Something you could try is

l_p_accumulator ?= i_p_accumulator->get_clone( ).

Hi,

DATA: l_p_accumulator TYPE REF TO cl_accumulator_trg,

Are you actually using a comma (,) instead of period, hope not.

Well, I tried to create a routine in my system and I do not get a syntax error.

If you still get an error you may try this.

l_p_accumulator ?= i_p_accumulator->get_clone( ).

.

Nope. I just pasted the required code. I have couple more declarations.

even the ? did not solve the error. Any more clues plz.

Hmm.. thats interesting.

Try to define the variable l_p_accumulator type ref to IF_ACCUMULATOR_TRG

Let me know if that helps.

Hi Prashant,

I tried this yesterday only and still the same error. My bad...I should have included that.

ANy more clues please.

Thanks,

Kiran

Infact when I add ? to the line, save and then do syntax check...? disappears automatically. so is this something to look into also?

Thanks,

Kiran

Hi Kiran,

This is really weird. When I try in my system, the code that you have given works fine. Surprizing!

As an alternative you may try this,

data l_p_accumulator type ref to object.
data method type string VALUE 'RESET_VALUES'.

Then call the method as

CALL METHOD l_p_accumulator->(METHOD).
