    Unanswered: Products and Parts Database

    I am working on my first access database project and I have come to a wall. I build products (about 20) and i buy parts to make those products (about 50). I need to create a form (basically a BOM) listing what parts I use to make each product and how much of that part i use. ie 3 x A screws, 5 x G Washers, etc.

    I would really appreciate at any Help i can get.

    ultimate goals would be:

    identifying all parts required to build a product and the qty and cost
    list of parts by vendor so i can keep track of cost changes

    ok...so heres the thought.

    tblPRODUCTS
    ProductID (PK)
    ProductName (text)

    tblVENDORS
    VendorID (PK)
    BusinessName (text)
    ContactInfo (text)

    tblPARTS
    PartID (PK)
    PartDescription (text)
    Vendor ID (PK from tblVENDORS)
    Unit Price (currency)

    TblBOM
    ID(PK)
    PartID(PK FROM tblPARTS)
    Qty Req (number)

    I think thats right. but how do i make sure that for Product A i can list all parts and their qty's. Form? Query? Will there be a table showing me that a particular part is part of that assembly of a product?

    This is what Im not able to grasp the understanding of.

    tblBOM also needs to include the ID of the parts that go into the product. You can design this table with a composite key, composed of the IDs of the product and its constituent parts.

    Alternatively, if you have multiple ways of making the same product, you can design a BOM header table and link that to a BOM details table instead.
    10% of magic is knowing something that no-one else does. The rest is misdirection.
