Hi Ashish,

1) Can you please tell me whether we can use DATASET statemnt for checking for a file in background whthether it exists or not.

Yes you can use the DATASET statement in background. In fact we use DATASET when we have

problems storing file on the frontend.

You can use OPEN DATASET statement and depending upon the SY-SUBRC value you will understand whether the file exists or not.

2) In cae the file does not exixts then how can i create a file and if the file exixts then i want to add some ros in the file.how can i do this?.

To create a file use OPEN DATASET..... FOR INPUT.

To add lines to the dataset USE OPEN DATASET ..... FOR APPENDING

3) Is there any way by which i can change the file name using dataset statement

I doubt whether you can change the file name. As far as I know the answer is NO.
