Field symbol Runtime error

[Former Member]

Hi,

I am using field symbol which has data already. I want to move that into a structure.. HOw do i acheive this ? I was trying the following but it is giving me a runtime error: "In unicode, the two structures have to be same structure"

FIELD-SYMBOLS: <ITAB> TYPE STANDARD TABLE,

DATA: LT_TAB TYPE TABLE OF mara,

LS_TAB LIKE LINE OF LT_TAB.

LOOP AT <ITAB> INTO LS_TAB.

APPEND LS_TAB TO LT_TAB.

ENDLOOP.

I had asked this ques earlier in the day as well and I recvd an answer "try assigning the value before the loop" but could not get it ?

any pointer to resolve this issue ??

you have to say loop at ls_tab assigning <itab>. That is the reason you would be getting an exception.

Hi,

Try this

FIELD-SYMBOLS: <ITAB> TYPE STANDARD TABLE,

DATA: LT_TAB TYPE TABLE OF mara,

LS_TAB LIKE LINE OF LT_TAB.

FIELD-SYMBOLS: <itab_line> TYPE ANY.

LOOP AT <ITAB> ASSIGNING <ITAB_LINE>.

LS_TAB = <ITAB_LINE>.

APPEND LS_TAB TO LT_TAB.

ENDLOOP.

Here is the Code for moving the data from internal table to field-symbol ....

REPORT  zprogram_one                            .
FIELD-SYMBOLS: <ITAB> like  mara. 
DATA: LT_TAB TYPE TABLE OF mara.

select *  from  mara   into  table LT_TAB .
break-point.
LOOP AT LT_TAB assigning <ITAB>.
.....
ENDLOOP.

reward points if it is usefull...
