DESCRIBE FIELD issue when calculation length

[Former Member]

Hi Experts

i am facing a issue with DESCRIBE LENGTH

my code is somewhat liek this

DESCRIBE FIELD <fs> LENGTH lv_len IN CHARACTER MODE.

here <fs> is of type P and its coming dynamically and gives dump that At the statment "DESCRIBE"

only character-type data objects are supported at the argument position "<FS>", but no strings are supported (data types STRING and XSTRING).

and just one more thing value coming in <fs> is sometimes decimal also like 78.20 .

Please help .

Sunny.

Hi. You could make a new variable:

data: lv_str(132) type c.
lv_str = <fs>.
DESCRIBE FIELD lv_str LENGTH lv_len IN CHARACTER MODE.

Hi Sunny,

Sorry about that... I should have run that code I guess...

This works for both type P and 😧

data: lv_str_fs type string.

lv_str_fs = <fs>.
CONDENSE lv_str_fs.
lv_len = STRLEN( lv_str_fs ).

Hi ,

Just one question ..do you need the length of the field or the length of the field content ?

If you need the length of the field then you have to give the name of the field in describe statement.

without knowing how your <fs> is getting populated its hard to give a solution.

if u want to find field content length then use following logic

DATA: linelength TYPE i VALUE 0.
DATA: text TYPE string.

text = 'L0593V1'.

 linelength = STRLEN( text ).
write linelength.

Try something like this,

data: lv_type type c.

DESCRIBE FIELD <fs> type lv_type. 

if lv_type CA 'CNDTS'.
DESCRIBE FIELD <fs> LENGTH lv_len IN CHARACTER MODE.
else.
DESCRIBE FIELD <fs> LENGTH lv_len IN BYTE MODE.
endif.
