DESCRIBE statement

Former Member — Wed, 21 Oct 2009 06:04:02 GMT

Dear all,

I m simply trying to get the length of a variable and written the following code.


DATA : var(20) type c,
       len type i.
       
       
 describe field var length len.
 
 write : /len.

But it giving an error : In Unicode DESCRIBE length can only be used with the IN BYTE MODE or IN CHARACTER MODE addition.

Can any one suggest some solution.

Regards,

Maverick

Tried F1 ?

DATA : var(20) type c,
       len type i.

describe field var length len IN CHARACTER MODE.

write:/ len.

else try with this as well

assign the char variable to string variable and use

gv_len = strlen ( string_name )

The error message clearly tells you to add either the IN BYTE MODE or IN CHARACTER MODE addition. What else is the issue you are facing here?

Describe is used to describe length of a field & how many number of lines for an internal table.

in case of field we have to provide in which format we have to read i.e. Character or Binary

in case of Internal Table no need to provide these things it will directly write number of lines to our field type integer.

*For Field

DESCRIBE FIELD dobj LENGTH ilen IN {BYTE|CHARACTER} MODE .

for more information go to F1 help

*For Internal Table

data:ivbap type standard table of <any table>,

da_tfill type i.

describe table ivbap lines da_tfill

HI,

Rewrite your code as

DATA : var(20) type c,
       blen type i,
       clen type i.



 describe field var length blen in byte mode.

 describe field var length clen in character mode.

 write : blen , clen.

here blen will give you the length in byte mode and clen in character mode.

Hi Maverick,

try this code.

DATA : var(20) type c,

len type i .

field-symbols <g1> type any.

assign var to <g1>.

describe field <g1> length len in CHARACTER MODE.

write : /' length :', len.

Hi Maverick

I am facing the same problem as you had encountered. May you share with me which is the correct syntax to use for DESCRIBE?

Thank you very much.
