concatenate field vbak-netwr

[joerg_arndt]

Hi Friends,

I have a small problem.

in the code below I got a short dump, says.

During concatenate the Operand <FS> is of Format "P" and it is not allowed, only strings.

do.

assign component sy-index of structure I_VBAK to <fs>.

if sy-subrc <> 0.

exit.

endif.

if sy-index = 1.

xout = <fs>.

else.

-> concatenate xout <fs> into xout separated by ','.

endif.

enddo.

How can I check and change the Data type of <fs> in this moment.

I have tried a cast like "field-symbols: <fs> type c" but I get only strange characters for this field vbak-netwr.

Can anyone help me?

Thank's Jimbob

what type of value u r getting into <fs>?

if it is a decimal value in decimal addition is mandatory.... like.....

Data: amount type P decimals 2.

Try to check with this.....

Hi Naveen,

it is of type 'P' .

The problem is "concatenate" can not proceed data of type 'P'.

So I have to change the type at runtime before concatenate the field. But how can I check the field type and change it to a string?

xout_final type string.

do.

assign component sy-index of structure I_VBAK to <fs>.

if sy-subrc 0.

exit.

endif.

if sy-index = 1.

xout = <fs>.

xout_1 = <fs>.

else.

-> concatenate xout xout_1 into xout_final separated by ','.

xout = xout_final.

clear xout_final.

endif.

enddo.

Thanks Jay,

but it does not work.

At last I did in this way.

But now I have all the empty 'N' fields filled with zeros.

data: xout_1 type string

clear xout.

do.

assign component sy-index of structure I_VBAK to <fs>.

if sy-subrc <> 0.

exit.

endif.

if sy-index = 1.

xout = <fs>.

else.

-> xout_1 = <fs>.

concatenate xout xout_1 into xout separated by ','.

endif.

enddo.

I'm looking for a way to check the format of <fs> at runtime and when it is 'p' I change it to 'c' or move the value to a string field.

Thank you anyway.

I doubt if you can check the format of field symbol, but I cam sure you can do it for variables

by describe field F1 type w_type.

if F1 is a type p then w_type will hold 'P'

F1 is a type n then w_type will hold 'N'.

hi,

try this way,

>data: filed_type(1),

> xout1(30).

>exit.

>endif.

>if sy-index = 1.

>xout = <fs>.

>else.

>describe field <fs> type filed_type.

>if field_type = 'P'.

>write <fs> to xout1.

>concatenate xout xout1 into xout separated by ','.

>else.

>concatenate xout <fs> into xout separated by ','.

>endif.

>endif.

>enddo.
