field symbol type any conversion error

k_gjergja — Fri, 09 May 2014 09:26:59 GMT

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>.

Hi Krsto,

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

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).

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?

regards,

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.

wt_final-value is char 50

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.

Edgar

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.

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.

Re: field symbol type any conversion error

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