field symbol type any conversion error

[k_gjergja]

Hello

I have  a field symbol

field-symbols:<wf_file> TYPE any. ,and the table  WT_file like  alsmex_tabline

(data : WT_file like  alsmex_tabline  occurs ) the field  wt_file-value  is of type CHAR 50 .

Later in a code  i have loop in  the table wt_file  moving the values to field  symbol

at the moment when wt_file-value = /1.3831  I have short dump because of the conversion issue .

Bach slash is there because  later is used as operand for division with 1.3831.

I am surprised because  field symbol is declared as  TYPE ANY .

Could i solve it if i declare field simbol as the same type as the table  wt_file is ?

Thanks

Krsto

LOOP AT wt_file.


wv_cnt = wt_file-col.
CONCATENATE 'WT_FINAL-FLD' wv_cnt INTO wlv_name.
ASSIGN (wlv_name) TO <wf_file>.
MOVE : wt_file-value TO <wf_file>.   " short dump when /1.3831
AT END OF row.
APPEND wt_final.
CLEAR  wt_final.
CLEAR  wv_cnt.
ENDAT.

ENDLOOP.

Hi Krsto,

You should :

CONCATENATE 'FLD' wv_cnt INTO wlv_name.

ASSIGN COMPONENT wlv_name OF STRUCTURE wt_final TO <wf_file>.

ASSIGN (wlv_name) TO <wf_file>.
MOVE : wt_file-value TO <wf_file>.   " short dump when /1.3831 

You should always check if the assignment is successful by checking the SY-SUBRC (or IS ASSIGNED, my personal choice).

BR,

Please read the post before posting a solution. The problem says:

 " short dump when /1.3831 

In the code there was no check after the ASSIGN statement that's what i was pointing out.

I prefer to check sy-subrc. Semantically IS ASSIGNED would be better, but consider:

ASSIGN (this) TO <fs>.

....

ASSIGN (that) TO <fs>. <------------ this could fail

IF <fs> IS ASSIGNED. <--------- but if the first one assign worked, then this will be true

do stuff.

ENDIF.

Valid point, but i have this habit of UNASSIGNing the field-symbol before every assignment (maybe an overkill)

ASSIGN (this) TO <fs>.

....

UNASSIGN <fs>. <------- Unassign the FS

ASSIGN (that) TO <fs>. <------------ this could fail

IF <fs> IS ASSIGNED. <--------- but if the first one assign worked, then this will be true

do stuff.

ENDIF.

I definitely think sy-subrc is more useful. Anyway Krsto assigned some points to himself so I think he finally understood his error.

[ThomasZloch]

Fortunately you cannot assign points to yourself, as this would result in SY-SUBRC = 4 or even a non-catchable IMMODEST_BEHAVIOUR short dump.

Hi Krsto,

Can you try by  ASSIGN statment instead of moving the value. It shoudl work.

[Former Member]

Hi Krsto,

it won't be of type any after the assign, so what type was field wt_final-fld... at the moment of short dump and what value was in wt_file-value?

Edgar

Hi ,

The value was /1.3831

Thanks

Ok but what type is variable wt_final-fld?

If it's a numeric type then your dump is normal.

Again, your field symbol is NOT of type any at the dump moment.

[k_gjergja]

wt_final-value  is char 50

Hi

If you are using same field symbol in two places, did you un assign first after the use.

The issue may be due to that. Just athought.

That's irrelevant Krsto,

It's when you assign the variable that you typify it:

ASSIGN (wlv_name) TO <wf_file>.

In this moment wlv_name is the name of the variable 'WT_FINAL-FLD' and some number.

What type is this variable? It's not the same as WT_FINAL-VALUE.

Regards,

Edgar

[gaurab_banerji]

Have you declared the field symbol <wf_file> with TYPE ANY or any numeric data type?

It probably got type casted to Numeric and thats why it cannot accept  a character one (due to the slash /) now.

Is the problem solved? kindly let us know.

Hi ,

Not yet , I sent proposal . The program is not in  my ownership. I will let you know .

Thanks
