Sort problem

I am having a problem with my ExtSort when my metadata comes out of the sort my data for the sort key is missing or not displaying it is there prior to the sort and I get know errors.

Sorry, but I don’t understand. Do you get a message? Or your data goes out unsorted?

I do not recieve a mesage and my data is properly sorted, when my data exits out of ExtSort my primary key column is missing it’s data.

I’m afraid I still don’t understand, where the problem is: error doesn’t occur and data is sorted. This is what one would expect from ExtSort.
The only idea I have is, that you have some null data. Nulls are regarded as as smaller than anything else, so they can be on the beginning of the output. Try to list more records, than default 10.
