using class's methods

[Former Member]

Dear All,

I have a question related to using a method of a class with parameters.

What is wrong with my code ?

DATA ref_Var TYPE REF TO CL_ABAP_STRING_UTILITIES.

Data sour(5) type c value 'First'.

Data dest type string.

CL_ABAP_STRING_UTILITIES->C2STR_PRESERVING_BLANKS( sour dest ).

It should be = not -

CL_ABAP_STRING_UTILITIES<b>=></b>C2STR_PRESERVING_BLANKS( sour dest ).

and the code should be

<b>call method CL_ABAP_STRING_UTILITIES<b>=></b>C2STR_PRESERVING_BLANKS

exporting

source = source

importing

DEST = dest.</b>

or

dest = CL_ABAP_STRING_UTILITIES<b>=></b>C2STR_PRESERVING_BLANKS( sour ).

Regards,

Ravi

hello,

call method is running but the second way with

or

dest = CL_ABAP_STRING_UTILITIES=>C2STR_PRESERVING_BLANKS( sour ).

returns the error message:

C2STR_PRESERVING_BLANKS does not have a Returning Parameter.

You can not use it in expressions.

Does it mean the second way is worng or is there onother alternative.

Hi Ilhan,

What the error message says is right. You cannot use the second code. Sorry for that. It should have a return parameter instead of the exporting parameter to use it that way. YOu have to use it the other way only.

Hi Ilhan,

Try this code:

report ZRTTEST .

Data sour(5) type c value 'First'.

Data dest type string.

call method CL_ABAP_STRING_UTILITIES=>C2STR_PRESERVING_BLANKS

exporting

source = sour

importing

DEST = dest.

write: dest.

Hi Ertas,

If CL_ABAP_STRING_UTILITIES is a static class then use

<b>CL_ABAP_STRING_UTILITIES=>C2STR_PRESERVING_BLANKS</b>

otherwise

create object and call like this

<b>ref_var->C2STR_PRESERVING_BLANKS</b>
