Hi Hai,

Check whether file[] is initial before going into the code that creates the file:

if not file[] is initial.

code to create file.

endif.

You can also do a describe on the table as well.

Hope this helps,

James.

check the content of line.

If not line[]/line is initial.

open dataset file.

Transfer line to file.

close dataset file.

endif .

How about checking your LINE before you open your dataset? Once you open the file, regardless of whether you have data, the file will be created. Are you using LINE as an internal table. If so, maybe use the following code:

CHECK NOT LINE[] IS INITIAL.

If there is no data in your table your file logic will be passed. That is assuming that is the remainder of your code for that particular part of your program (FORM).

Good Luck!

Check the number of line if you have an internal table ( describle table itab lines w_line.

check w_lines ne 0.

Or you can check the line you transfer are not equal to 'space'.

You seem to have only one line ( regarding your code ) :

if line ne space

open dataset file.

Transfer line to file.

close dataset file.

endif.

Here is what I would so.

for internal table approach (data is in a internal table)

loop at itab.

at first.

open dataset file.

endat.

move itab to line.

transfer line to file.

at last.

close dataset file.

endat.

endloop

no internal table

if not line is initial.

open dataset file.

Transfer line to file.

close dataset file.

endif.
