Hi Yves,
I just tried with DDL statement and it created a SQL file . You were mentioning about if its not BW system it will not generate any file . I just gone through the Guide , it was not clear though . and it generated SQL file with only 1KB .
Export is still running and its around 60GB so far. still got 4 more to complete.
I was not able to update R3 files this time . If this export fails or any issue , surely I will try with that option too.
Thanks
