I provide this simple script for the QVD log creation when there is no records loaded
LOAD * Inline
LET vNoOfRow = NoOfRows('Tab');
If $(vNoOfRow) = 0 Then
'No Data Received on '&Now() as Status
STORE Status into Status.txt(txt);
By this we get the QVD status that the file is not having the No data on particular folder location also
And if you try to load it with some data then the status Qvd not loaded.
