How to define a TYPE REF TO data into my local variable/structure?

Former Member — Tue, 19 Apr 2011 02:45:46 GMT

Hello,

I am trying to implementing a BADI, in its signature part,

 c_accit TYPE REF TO data.

My pseudo code goes like,

 DATA: l_itm_details TYPE REF TO data.
l_itm_details = c_accit.
l_itm_details-koart = 'D' =====> here am getting error!
* Do processing
ENDIF.

Here am getting error that, l_itm_details is not a structure! Pls. let me know how to fix it?

Thank you

Hi Raju,

I am not sure what this data is.i.e. class or structure.

I am assuming that it is a structure. In your code what you have done is only declared references but not created the instance.

Please try the below code it will resolve your problem.

DATA : c_accit TYPE REF TO data.

l_itm_details TYPE REF TO data.

CREATE DATA c_accit.

l_itm_details = c_accit.

l_itm_details->koart = 'D' .

Hope it will resolve your problem.

Hello,

c_accit TYPE REF TO data.

C_ACCIT is a "data reference" parameter. In order to access its components you have to "de-reference" it!

FIELD-SYMBOLS: <l_itm_details> TYPE ANY,
<l_value> TYPE ANY.

ASSIGN c_accit->* TO <l_itm_details>."De-reference the data reference

ASSIGN COMPONENT 'KOART' OF STRUCTURE <l_itm_details> TO <l_value>.

If you know the structure of the data reference variable you can define your field-symbol <l_itm_details> of that type directly, else you can define a generic type as mentioned in the code snippet.

BR,

Suhas

 ASSIGN c_accit->* TO <l_itm_details>."De-reference the data reference

Here pls. let me know,

1) What will do the symbol of

->*

and how do we call it?

2) What does mean of 'De-reference'

Thank you.

You call '->*' just as Suhas explained. That symbol is called the de-referencing operator and it merely serves to give the field-symbol the value of the data object in the storage area. You can read more about it in the help files on ASSIGN. De-referencing' just means de-coding the value of a data reference.
