We are still having issues with the Excel reader where the mapping style of "By Field Heading" is not picking up columns by field headings.  It has repeatedly wiped out product data whenever the spreadsheet is modified.  This happens if you run the job via schedule without first confirming that the fields match.

The issue is that IMan ALWAYS uses the position (1, 2, 3, etc) and not the field heading ("sku", "name", "description", etc).

If you have columns, A, B, D, and you add a column C between B and D, when IMan is building the dataset it will attempt to put the data from C into D because D was the third column the last time the job was opened.

This is high priority for us as it has destroyed the product data for a few production sites.
