We have our top level assembly of supply type BUILD with BOM components. BOM components have sub-assemblies with supply type as purchase and the default cost and the purchase price has been set up for those. These Purchase type assemblies do not BOM components. Whenever I roll up, it is not calculating the components cost and rolling up the cost for the top level assembly. ITEM A (Supply Type = Build, top level assembly) --ITEM AB (Supply Type = Build with BOM components) ----ITEM ABC (Supply Type = Purchase, no BOM components) - Standard Cost = $10 ----ITEM ABD (Supply Type = Purchase, no BOM components) - Standard Cost = $15 When I run the cost roll up, I don't see $25 breakdown in the planned standard cost, it shows me as $0 for ITEM A. Any help is appreciated!! #standardcosting
