I dont believe that there is a standard report for what you are asking for… also, the act of rolling up is different than POSTING the value change. if you want to know what parts had a value change due to a rollup, you might want to look in the parttran table for the cost change transaction (Transaction type ADJ-CST)
Yeah @aoropeza “rolling up” and “posting” are two separate things. You can hit ACtions>Roll Up as many times as you want in the costing workbench. Are you asking for that information? Or…?
