The first worksheet of each excel file is used to determine the price of the precious and base metals. These prices are used throughout the rest of the worksheets. My database will just create a table to store these values and call them when the time comes.
A single quote can contain one or all of the following elements: Individual External Part, Individual Internal Part, or Assembly.
An assembly can contain either an Individual Sub Part (which can be Internal or External), or a Sub Assembly which can again contain either an Individual Sub Part (which can be Internal or External).
The second worksheet is where most of the data is entered. The sequence for an Individual External Part goes as follows:
Part Number, Description, EAU (Estimated Annual Usage), MinBatch (Minimum Batch Required, used to determine whether the quote is per piece, or per 1,000. if value > 5,000 then quote is per 1,000.), FabPrice (*See note below*), [This is where the metals will be entered. In the excel sheet there are columns specific to the metal, the database will allow any metal to be entered at this stage.]. The only other things on this worksheet are calculated fields.
*The table at the top of the page is used if the part is Internal. This table is used to calculate the "FabPrice" field.*
The third worksheet is once again about metal prices.
The fourth worksheet is where all of the rest of the calculations are made.
the fields that contain data to be entered are as follows:
Number Of Handling Operations (used to calculate cost for Handling), Import Duty (used to calculate the shipping and import duty, if yes.), the other field is Margin Fab % (My boss wants the database to determine this field automatically).
The assemblies are similar in many ways.
I hope this helps. I focus on the Individual Part because it is the easiest, and the assemblies work off of the same process, but used the data is a slightly different way.
