Field-Symbol Problem

Former Member — Tue, 24 Oct 2006 10:13:22 GMT

D/A,

Please help me out in analyzing the root cause of the error appearing when i am trying to execute a module pool program.

Top Include :

constants cw_dokob type drad-dokob value 'ASMD'.

Short Txt column on the Table control

DATA: W_DKTXT TYPE MCDOK-DKTXT.

To store the dynpro column info

DATA: T_TAB TYPE TABLE OF CXTAB_COLUMN.

to populate T_TAB at first run of this program

DATA: W_FIRST_RUN TYPE XFELD VALUE 'X'.

constants cw_dokob2 type drad-dokob value 'PLKO'.

MODULE call_object_pbo

FIELD-SYMBOLS <FS> TYPE ANY.

CLEAR W_DYNNR.

clear w_dokob.

On first run of this program Store the Table control configuration

IF W_FIRST_RUN = 'X'.

CLEAR W_FIRST_RUN.

T_TAB[] = TAB_X1-COLS[].

ENDIF.

IF <FS> = cw_dokob.

W_DYNNR = '9001'.

W_DOKOB = CW_DOKOB.

ELSEIF <FS> = cw_dokob2.

W_DYNNR = '9002'.

W_DOKOB = CW_DOKOB2.

endmodule.

Thanx,

Akhil

when i m executing this piece of code,dump is being thrown with a reason that "Field symbol has not yet been assigned."

Hi,

This is because you are checking IF <FS> = cw_dokob without assigning values for field symbols.

U need to assign value/data to Field symbol before using it.

example

ASSIGN (w_cwdokob) to <FS>.

In the above it would assign the value of variable w_cwdokob to the field-symbol.

Hi Akhil,

You haven't assigned any value to the field symbol but directly using it in a If condition.

YOu must assign some value before you use it.

FIELD-SYMBOLS <FS> TYPE ANY.

CLEAR W_DYNNR.

clear w_dokob.

On first run of this program Store the Table control configuration

IF W_FIRST_RUN = 'X'.

CLEAR W_FIRST_RUN.

T_TAB[] = TAB_X1-COLS[].

ENDIF.

IF <FS> = cw_dokob.

W_DYNNR = '9001'.

u declared the fs fine..but u never assigned it to any varible. but u have used it in a logical expression. you need to assign a field to a fs which then will act as a pointer. look for 'ASSIGN' key word in f1 help

Assign some structure to <FS>.

Only then the field-symbol becomes meaningful enough to be used.

you need to assign adress to the "pointer"

for example :

ASSIGN (FIELD) TO <F_FS4>.

<F_FS4> = ST_ITAB-RAST1.

Hi,

dump is due comparison of value

fields symbol before assigning .

assign fld1 to <FS>.

<b> IF <FS> = cw_dokob.</b>

W_DYNNR = '9001'.

W_DOKOB = CW_DOKOB.

<b>ELSEIF <FS> = cw_dokob2.</b>

W_DYNNR = '9002'.

W_DOKOB = CW_DOKOB2.

endmodule.
