Hi kartik,

my code is like :

data : begin of itab occurs 0,

NO_OF_BOX TYPE TLINE-TDLINE,

end of itab.

data: name type THEAD-TDNAME.

DATA lt_text TYPE tline occurs 0 with header line.

CALL FUNCTION 'READ_TEXT'

EXPORTING

id = 'B01'

language = sy-langu

name = name

object = 'EBAN'

TABLES

lines = lt_text.

loop at lt_text.

MOVE lt_text-TDLINE TO i_TAB-NO_OF_BOX.

IF NOT I_TAB-NO_OF_BOX IS INITIAL.

exit.

ENDIF.

endloop.

MODIFY I_TAB.

ENDLOOP.

Please Help me

hi ankita please clarify the following points.


data : begin of itab occurs 0,
NO_OF_BOX TYPE TLINE-TDLINE,
end of itab.

data: name type THEAD-TDNAME.

DATA lt_text TYPE tline occurs 0 with header line.

CALL FUNCTION 'READ_TEXT'
EXPORTING
id = 'B01'
language = sy-langu
name = name
object = 'EBAN'
TABLES
lines = lt_text.

loop at lt_text.
MOVE lt_text-TDLINE TO i_TAB-NO_OF_BOX.

IF NOT I_TAB-NO_OF_BOX IS INITIAL. " i think problem lies in this condition as soon as first line is read the condition becomes true and exits the loop. so re-think about this condtion

exit.
ENDIF.
endloop.


MODIFY I_TAB.  "why these two lines
ENDLOOP.         " which loop is it

Why are u putting the condition inside the loop at lt_text since ur exiting at condition u r not able to read all lines of text.

Hi kartik...

I am using this code because I want to modify my internal table field..

If i am not using it , only blank value store in internal table.

IF NOT I_TAB-NO_OF_BOX IS INITIAL.

exit.

ENDIF.

Hi ankita,

See.

What ur code is currently doing is reading one line then

checking this condition

IF NOT I_TAB-NO_OF_BOX IS INITIAL.

exit.

ENDIF.

Condition is true so it exits.

So its not reading other lines.

do like this


CALL FUNCTION 'READ_TEXT'
EXPORTING
id = 'B01'
language = sy-langu
name = name
object = 'EBAN'
TABLES
lines = lt_text.
if sy-subrc = 0. "  This is important
loop at lt_text.
concatenate  i_TAB-NO_OF_BOX  lt_text-TDLINE to  i_TAB-NO_OF_BOX.
endloop.
endif.

MODIFY I_TAB. "here if u want u can put this check IF NOT I_TAB-NO_OF_BOX IS INITIAL. but i think its not required as now we are looping at lt_text only if sy-subrc is 0

Thanks kartik...

It works but last some text is missed..

is there any limit for character...

because it shows only 130 characters...

Re: problem in read_text function

size limit depends on data type of this i_TAB-NO_OF_BOX

just check it, probably u wud require to change its data typeto extend it.
