error in loop at itab in ECC 6.0

Former Member — Fri, 30 May 2008 13:51:14 GMT

hi,

in ECC 6.0, in an abap proxy class i have a loop statement as follows:

LOOP AT tablename.

sdfsdf

sfsfsf

fsf

ENDLOOP.

and i get the error, At "Loop At itab" one of the additions into/assigning or transporting no fields is required in OO context !! what does that mean ? in my abap proxy class can't i use the loop at statement's simplest form ?

whats the solution ?

use a workarea

hi,

in OO conetxt you cannot use internal table with header line, so you have to LOOP through the table INTO a work area or you have to ASSIGN a field symbol.

LOOP AT itab INTO wa .

...

ENDLOOP.

hope this helps

Hello.

Is that tablename an input structure of the proxy?

You must create a work area for it, and then use:


LOOP AT tablename INTO wa.
...
ENDLOOP.

Best regards.

YOu can't use the normal internal table declared with OCCURS 0 extention in OO programming

You need to have the internal tables declared with type and you have to explicitally take the current row into the workarea.

Like:


types: begin of ty_tab,
field1 type vbeln,
end  of ty_tab.

data: tablename type standard table of ty_tab,
wa_tab type ty_tab.

LOOP AT tablename into wa_tab.
wa_tab-vbeln = 'XXXX'.

ENDLOOP.

Hi,

In the OO concept we should not modify or process an internal table direcly.

A work area must be used for this purpose. The error will be thrown if WA is not used.

It means it can only use an internal table without header line, so it needs to create a workarea in order to see the data of a record of the table:

DATA: WA TYPE TABLENAME.

LOOP AT tablename INTO WA.
ENDLOOP.

Sure you can, you just have to use an explicit workarea and use the INTO.

Types: begin of ttab,
            fld1 type c,
           fld2 type c,
          end of ttab.


data: itab type table of ttab.
data: wa like line of itab.

Loop at itab INTO wa.

* Now the row is stord in WA, do what you need to here.

endloop.

YOu can NOT use internal tables with header lines in the OO context.

You need to use work area when you are working with Object Oriented environment. I hope you are using the loop inside class or BSP or WDA or some BADI

LOOP AT ITAB INTO WA. use work area for all internal table processing.
