Component Requirements
As shown above, the Requirements window lists the assemblies that are found on the selected orders, with the required quantity and shortage quantity. If you want to build these items you need to see a list of the components that you need to have on hand.
As with other features of CCRQBOM you have the option of doing a single level or full level explosion. Full level will “explode” any subassemblies into their component parts, single level will not. Typically you will look at the full level explosion.
Note the box titled Use SubAssembly. If this is not checked then the application will ignore any on hand quantity that you have for subassemblies that will be used, if you do a full level explosion. If you check the box then if a quantity of a subassembly is required, the application will consume those before it will “explode” the subassembly BOM to make more.
The Quantity option lets you pick the column to work with for the quantity used to generate the requirements. Quantity uses the quantity column - four of assembly 0050-MC in our example. Shortage uses the shortage column – one of assembly 0050-MC in our example. Typically you would be using the shortage value, which represents the number of assemblies that you don’t have on hand already. In some cases you may want to use the quantity value, if you want to see the number of parts needed to build ALL of the required assemblies, even if you have some on hand.
You can choose to work with just some of the assembly items listed by selecting the assemblies in the list and clicking Process Selected button. Typically you will want to see the aggregate requirements from all assemblies listed, so you would click the Process All button.
For our example we will click Process All, with the Quantity option selected. The program will make its calculations and display the following window:
This looks very similar to the prior screen, but there are several differences. Note that there are several tabs on the grid (Requirement, Aggregate and Result), and two reports listed in a menu at the top.
If you click on the Result tab you will see a listing of the high level assemblies that were processed. Normally you will see a status of “OK” by each item – you should take a quick look here to see if there were any problems. In some cases there may be a problem with processing an item, and the problem will be listed here. This should not be a common occurrence, but it is always best to check.
