Hello, What are the best steps to standard costing? 1. We have several assemblies, both of type BUILD and PURCHASE. 2. We have several levels, example, Grand Parent or Top-Level Assembly, its components (having its own sub-assemblies and components). 3. The components, are of type PURCHASE and do not have any further breakdown. 4. Some sub-assemblies are of BUILD type and have components of their own. 5. Like that we have many levels, some go up to 11 levels. 6. All are assemblies with non-inventory and / or other charge items. We do not have inventory types. 7. We have updated the standard cost for all purchase type assemblies and other items except for the BUILD types. What would be the best practice to make sure that the Top-Level or Grand parent assembly's roll up cost includes the cost of all the components of its sub-assemblies as well? Thanks,
