I have an array function that brings in the margins for pricing from
another sheet in the workbook. Currently, it has about 13,000 part
numbers on it. . . .

The other worksheet has 13,000 part numbers on it?

When I copy the formula normall, I use the drag box on the cells. . . .

OK, have you tried to copy the cell containing the presumably single cell
array formula, then select the range into which you would have filled it,
then paste into that range?
