Hi!

I didn't get your question. If you are appending instances in your internal table, then what is the need of key in that table?

I believe BELNR is some kind of account number ... so it must be unique identifier...

(Basically there should be a unique identifierr.. lets say it is ACC_NO )

So try out this ..

loop at my_belnr into wa_belnr where object->acc_no = <your value>

Here .. object is the field in the internal table where the object ref is stored ..

and Assumption is that ACC_NO is public ... so object->acc_no can be accessed..

This works..

Tm,

have a requirement that i haev to

loop at my_belnr into wa_belnr with key : ....

there is no such syntex we have in SAP.

i think you need to loop then use read for reading my_belnr.

Hello Trivenn

First a remark to your coding sample:


my_belnr type ref to table of <other_calss> .  " Syntax incorrect -> guess you mean a table type of references
wa_belnr type ref to <other_class>.

If my assumption is correct (see comment above) then you can access your instances quite easily:


" Assumpting: the instances collected in the itab have a public key attribute BELNR.

" Recommendation: your naming conventions are a mess -> use better ones:

DATA: lt_account     TYPE <table type with line type: REF TO <account class>,
          lo_account     TYPE REF TO <account class>.

" LOOP statement:
LOOP AT lt_account INTO lo_account
                               WHERE ( table_line->belnr = <...> ).
...
ENDLOOP.

" READ statement:
READ TABLE lt_account INTO lo_account
          WITH KEY table_line->belnr = <...>.
...

Herr Schieferstein,

Vielen Danke.

I apologise for not putting the code in the question properly and not correct question either. i wanted to generalize the question.

well my requirement is that i have to read the table my_belnr which is attribute of a class.

Can i read it like this

read table lt_account into lo_account with key (belnr) ?

Hello Trivenn

No need to apologize for anything.

However, I still do not fully understand the typing and contents of your itab my_belnr.

Perhaps you can paste your coding. Then it should become clear.

method CONSTRUCTOR.

DATA: ls_record type /evuit/exch_vbel.
DATA: ls_beleg type ref to /evuit/exch_prd_vert_nn_belgv2.

   my_header = i_header.
	
	LOOP AT i_records INTO ls_Record.
	   ls_beleg = me->FACTORY_BELEG( i_record  = l_record ).
	   APPEND ls_beleg TO my_belege.
	ENDLOOP.
endmethod.


method send.

DATA: Ls_beleg type ref to /evuit/exch_prd_vert_nn_belgv2.

read table my_beleg into ls_beleg with key u_status = co_avis .


endmethod.

Hello Trivenn

The definition of my_belege is still missing yet it should be clear how it looks like.


method send.

" NOTE: Assuming that U_STATUS is a PUBLIC instance attribute you should be able to write:
 
DATA: Ls_beleg type ref to /evuit/exch_prd_vert_nn_belgv2.
<span style="color:red">
  READ TABLE my_beleg INTO ls_beleg
    WITH KEY table_line->u_status = co_avis.
</span>
 
endmethod.

Dear Uwe,

Now i understand that my_beleg must have public attribute u_status. and that this status must be filled by the constructor.

Thank you very much.

Regards.
