Types of Assembly Page #3
On the previous page we showed a Muli-Level Bill of Materials containing a number of sub assemblies. All versions of miniMrp can also display and process a BOM in Single Level mode. A Single Level BOM.
The image to the right is still the same product that you saw on the previous page but in single level mode the BOM only shows the top level. If you processed this BOM then only the items at this level will be issued (their OnHand quantities would be adjusted/reduced) In single level mode miniMrp will assume that the assemblies, Items 4, 5 and 6 have already been built and they would be taken out of your inventory.
It's clear then that previous versions of miniMrp only gave you two options - to issue "all levels" or "top level only". There was nothing in between. For many users, this is exactly what they want to do. But this version of miniMrp introduces a new type of sub assembly. "CSAS" (Closed Sub Assembly) giving you more flexibility. Take a look at the BOM in the image below - it's the same product that you saw on the previous page except in this example some of the sub assemblies are of type "CSAS". This is still a multi-Level BOM but the components inside closed sub assemblies remain hidden.
In this BOM you can see that Item 4 is an assembly of type ASSY. Item 4 is a standard assembly and miniMrp breaks it down to its component parts showing items 5, 6, 7, 8 and 9 at level 2.
If you were to issue this BOM then miniMrp would assume it needs to build item 4 so it would not be issued. Instead it would issue its components (items 5 through 9) so that Item 4 can be built as part of the same works order. Items 10 and 11 are also assemblies but they belong to the type CSAS. They are "Closed Sub Assemblies". This tells miniMrp to assume that they already exist in your inventory. When this work order is issued those sub assemblies would be taken directly out of inventory. Note: miniMrp version 4 introduced a new 'Build for Stock' feature which allows you to maintain an inventory of ready built sub assemblies. Change the 'Type' of such sub assemblies to "CSAS" and this tells miniMrp to assume that when they appear in a BOM they will always exist in your inventory and such sub assemblies will be issued from stock.
