Hi Alicia,

This is the current expected behavior on export. I don't have any other suggestions beyond those that you already mentioned in terms of how to include both the "real" value and the missing value indicator in the output. We made the decision to include just the "real" value in the export case because it caused problems for many downstream tools when there were mixed types in a single column. For example, having integer or date values for many rows, but a string missing value indicator in others.

In your usage scenario, are "real" values and missing value indicators mutually exclusive, or do some rows have both?

Thanks,
Josh
