Bill of Material costing report

I executed the BOM cost report for PN SSP-100(Avg Cost) and first part listed, PN 102-1(Avg cost), does not have any cost listed in the BOM costing report whereas I checked the PN 102-1 have cost in the part tracker.

This is very old BOM and the parts have not changed. Any thoughts?

I think, I have to run the cost rollup to see the BOM Cost. Hope, cost rollup can be run for purchased type part.

I ran the cost rollup but still the cost is not updated. Any thoughts?
