an error about internal table

Former Member — Fri, 19 Oct 2007 12:47:20 GMT

Dear all,

I wrote a following program, but got an error.

REPORT Z_SIMPLE_ITAB.

data : begin of line,

num type i,

sqr type i,

end of line.

data itab type standard table of line with key table_line.

do 5 times.

line-num = sy-index.

line-sqr = sy-index ** 2.

append line to itab.

enddo.

loop at itab into line.

write : / line-num,line-sqr.

endloop.

Error Message

A line of "ITAB" and "LINE" are not mutually convertible. In a Unicode

program "ITAB" must have the same structure layout as "LINE"

independent of the length of a Unicode character. Unicode character.

Thanks you

HI,

Change this

data itab type standard table of line with key table_line.

data itab type table of line.

try declaration like this:

types: begin of tp_line,

num type i,

sqr type i,

end of tp_line.

data : itab type standard table of tp_line ,

line type tp_line.

clear line.

refresh itab.

do 5 times.

line-num = sy-index.

line-sqr = sy-index ** 2.

append line to itab.

enddo.

loop at itab into line.

write : / line-num,line-sqr.

endloop.

Hi John,

do like this

REPORT Z_SIMPLE_ITAB.

types : begin of ty_line,
num type i,
sqr type i,
end of ty_line.

data: itab type standard table of ty_line.
        line type ty_line.

do 5 times.
line-num = sy-index.
line-sqr = sy-index ** 2.
append line to itab.
enddo.

loop at itab into line.
write : / line-num,line-sqr.
endloop.

Hi..

Change this way...

REPORT Z_SIMPLE_ITAB.

data : begin of line,

num type i,

sqr type i,

end of line.

<b>data itab LIKE standard table of line .</b>

do 5 times.

line-num = sy-index.

line-sqr = sy-index ** 2.

append line to itab.

enddo.

loop at itab into line.

write : / line-num,line-sqr.

endloop.

Reward if helpful.

hi John,

you cannot create internal table this way. pls. try:

Type

TYPES : BEGIN OF ty_line,

num TYPE i,

sqr TYPE i,

END OF ty_line

Work area

DATA : gw_line TYPE ty_line

Internal table

DATA : gt_line TYPE TABLE OF ty_line.
