Length of a transparent table(structure)

[Former Member]

Hi

I have the following table

say YYTAB...it has 2 fields of size 3 and 4.

How to find its total size?

I mean i shud get the output as 7.(Sum of the sizes of its fields)

is there any function module?

Check for table DD03L contains the output length . Make select in this table with table name as YYTAB and sum it up

data : v_field1 like YYTAB-field1.

data : v_field2 like YYTAB-field2.

data : v_i type i,

v_i1 type i,

v_i2 type i.

describe field v_field1 length v_i1 in character mode .

describe field v_field2 length v_i2 in character mode .

v_i = v_i1 + v_i2.

write 😕 v_i.

Hi,

another way:

TYPES: BEGIN OF lty_xyz,
...
       END OF lty_xyz.

DATA: ls_xyz TYPE lty_xyz.  
DATA: lv_length TYPE I.
DATA: lv_length_comp TYPE I.
FIELD-SYMBOLS <comp> TYPE ANY.
...


CLEAR lv_length.
DO.
  ASSIGN COMPONENT sy-index OF ls_xyz TO <comp>.
  IF sy-subrc <> 0.
    EXIT.
  ENDIF.
  lv_length = lv_length + lv_length_comp. 
ENDD0.

Kind regards,

HP

The "describe field" command works also with the structure name. There is no need for a loop.

 describe field YYTAB length v_i1 in character mode

@Henry,

In Character mode isn t working. The table has both c and i fields... Its not unicode compatable rite?

[former_member194797]

In this case ask it in byte mode:

describe field YYTAB length v_i1 in byte mode

@Henry.

But iam getting the length as twice...

say 14 instead of 7(taking above example) , if u use byte mode.
