Hi,
to open a data set, you need to have the path for the application server file, to see the application server files. goto AL11 transaction code, there you will find the directories then inside it you will find sub directories then you will find the file names, there you need to open the file using the open datasets ..
you have written DATA : FNAME(90) VALUE 'j:/ hai.txt'. , but this is not a application server file name, just goto AL11 then you will find the file names and give the correct path
