Best regards.

data: g7(3) type n,

PR TYPE I,

tx_it1(36),

fkimg type p decimals 3.

fkimg = 2480 .

SY-TVAR0 = fkimg.

g7 = SY-TVAR0+12(3).

write : / g7.

This is calles as offsetting. 12 is the positiona dn 3 is the number of char to be extracted.

eg. g_text = 'SAPABAP'.

g_text4(4) will be ABAP.

Hello Barath Srinivas,

let me correct your statement:

when g_text = 'SAPABAP1'.

g_text+4(4) is NOT "ABAP" but "BAP1"! +4 is the 5th position in the string.

In your case g_text+4(4) (with the value SAPABAP) causes a dump because your field does have only the length of 7.

HI,

fkimg is a pack type field.so while assigning it to sy-tvar0(Text Variable for Placeholders in List Headers)

then it will be assigned as 000000000002480.000

so sy-tvar0+12(3) = 480.

rgds,

Hello dongdong,

SY-TVAR0 is a 20 Char field.

fkimg contains the value 2480.000. After moving fkimg to the character string, SY-TVAR0 looks like (in ASCII): "2020202020202020202020323438302E30303020".

g7 = SY-TVAR0+12(3) selects the 13th byte of SY-TVAR0 in the length of 3, i.e. the value of g7 is "343830" or 480.

I hope this helps,

Hi,

This is an offsetting technique. Offsetting is fit for certain data types.The following sample code will give you some perception regarding the offsetting technique.

Note : use debug mode.

data : date like sy-datum,

var(10).

start-of-selection.

concatenate date6(2) '.' date4(2) '.' date+0(4) into var.

end-of-selection.

write : /1 var.

Reward if useful.

the length of variable SY-TVAR0 is 20 and it is right justified.

so when you fkimg to SY-TVAR0, the value in the variable fkimg(2480) is rigt justified to SY-TVAR0 and padded with spaces on the left side.

when you use g7 = SY-TVAR0+12(3), this will retrieve 3 chars from left starting from 12th posiion.

Hi,

Pls refer below statements,

fkimg = 2480 .

Now fkimg is 2480.000

SY-TVAR0 = fkimg.

SY-TVAR0 has 20 char.

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

+2 4 8 0 . 0 0 0 /-

so at 12th position 4 is stored. so while using the offset

12(3) u will get 480.

Reward points if it is useful
