finding length of variable at run time

[Former Member]

Good Morning to all Guru's,

can anybody explains me how i can find out the total length of one field from the internal table at run time?

example.

i wanted to some thing like this.

TYPES:BEGIN OF text12,

text1 TYPE string,

num(4) TYPE n,

calc TYPE i,

off TYPE i,

off1 TYPE i,

END OF text12.

DATA:wa TYPE text12.

DATA:itab TYPE TABLE OF text12.

MOVE 'i know you know' TO wa-text1.

MOVE 1234 TO wa-num.

MOVE 5678 TO wa-calc.

APPEND wa TO itab.

LOOP AT itab INTO wa.

FIND 'you' IN wa-text1 MATCH OFFSET wa-off.

• FIND (wa-num) MATCH OFFSET wa-off1 . "here i am strucked

SHIFT wa-text1 BY wa-off PLACES.

SHIFT wa-num BY 2 PLACES.

SHIFT wa-num BY wa-off1 PLACES.

WRITE:wa-text1,wa-num,wa-calc.

ENDLOOP.

Please help me out.

Thanks

hi,

Use DESCRIBE FIELD statement.

Hi,

Use STRLEN() to find total data length of a field.

Hi

use strlen(fieldname) it will give you the length.

you can also use describe fieldname for that just pass the itab field to a temp variable and say DESCRIBE on that

reward if helpful

Hi Priya,

Try This code If it suffices ur requirement. Award Points if useful.

TYPES:BEGIN OF text12,

text1 TYPE string,

num(4) TYPE n,

calc TYPE i,

off TYPE i,

off1 TYPE i,

END OF text12.

DATA : l(5) TYPE n.

DATA : t(5).

DATA:wa TYPE text12.

DATA:itab TYPE TABLE OF text12.

MOVE 'i know you know' TO wa-text1.

MOVE 1234 TO wa-num.

MOVE 5678 TO wa-calc.

APPEND wa TO itab.

LOOP AT itab INTO wa.

FIND 'you' IN wa-text1 MATCH OFFSET wa-off.

FIND wa-num IN wa-num MATCH LENGTH l.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'

EXPORTING

input = l

IMPORTING

output = l.

FIND l IN wa-num MATCH OFFSET wa-off1.

SHIFT wa-text1 BY wa-off PLACES.

SHIFT wa-num BY 2 PLACES.

SHIFT wa-num BY wa-off1 PLACES.

WRITE:wa-text1,wa-num,wa-calc.

ENDLOOP.

hi priya

try like this

TYPES:BEGIN OF text12,

text1 TYPE string,

num(4) TYPE n,

calc TYPE i,

off TYPE i,

off1 TYPE i,

name type string,

name1 type string,

END OF text12.

DATA:wa TYPE text12.

DATA:itab TYPE TABLE OF text12.

data: len type i,

num type i.

MOVE 'i know you know' TO wa-text1.

len = strlen( wa-text1 ).

num = 0.

do len times .

num = num + 1 .

*MOVE wa-text1(num) TO name.

move wa-text1(num) to wa-name .

enddo.

MOVE 5678 TO wa-calc.

APPEND wa TO itab.

LOOP AT itab INTO wa.

FIND 'you' IN wa-text1 MATCH OFFSET wa-off.

• FIND (wa-num) MATCH OFFSET wa-off1 . "here i am strucked

SHIFT wa-text1 BY wa-off PLACES.

SHIFT wa-num BY 2 PLACES.

SHIFT wa-num BY wa-off1 PLACES.

WRITE:wa-name ,wa-num,wa-calc.

ENDLOOP.

LOOP AT itab INTO wa.

FIND 'you' IN wa-text1 MATCH OFFSET wa-off.

• FIND (wa-num) MATCH OFFSET wa-off1 . "here i am strucked

SHIFT wa-text1 BY wa-off PLACES.

SHIFT wa-num BY 2 PLACES.

SHIFT wa-num BY wa-off1 PLACES.

WRITE:wa-name ,wa-num,wa-calc.

ENDLOOP.

in this wa-off is i so change the off type is c

then its work fine.
