Hi,

You can check out the results through sy-subrc. it may take values 0,4,8 etc..

for complete details do F1 on OPEN DATASET you can see different values & reasons for the same.

Hi,

This statement fails always in the production system only. In our development server it always run perfectly.

Is there any specific reason why this fails only in production system.?

When it's fails what do I have to do to make it happen. It means I have to overwrite the text file always. If it fails how to make it happen.?

Regards

Hi,

Handling error is not enough for me.

The text file I am try to create have to create always. When it fails What do I have to do to recreate it.

Hi,

Whenever you open the file in OUTPUT mode, if the file already exists, then SAP will overwrite it & if it doesnt exists, then SAP will create a new one.

You dont have to worry @ it.

The only problem for an error could be if you dont have authorization to access the folder. In that case you need to use some other path for which you have authorization.

Hi,

Thanks and u are correct. If the text file is there it overwrites and if it is not it creates.

But my issue is when I run at first time it creates the test file and when I run it second it give me the message 'No such file or directory'.

What do I have to do for this.?

Best regards
