Hi anbu23,

I did try your code.
It worked for my test data set.
But it seems like no work if my data set is huge?

Do you have any better idea?
Thanks.

Hi anbu23,

I plan to sort primarily by field 3 and
secondarily by field 2 which is general numeric value.
If small data set, your command looks fine.
But it can't generate desired output if the data set is larger Smilie
