Items are the customer's internal part number that defines the requirements for the parts on AML (Approved Manufacturers List). Parts on AML are the manufacturer parts that fulfill the items requirements. All parts on AML for an item are / should be form-fit-function equivalents of each other. When assembling the product, any part on AML for the item can be mixed in the same bin – each will work and fit the same way. AML statuses recognized by BOM Advantage include Preferred & Contracted, Preferred, or Alternate.
If you have a PLM system, you can likely export the Bill of Materials in the Product Data eXchange (PDX) format. Note that this is the preferred format. PDX handles AML structure, character encoding, and escaping issues much more robustly than other formats. That is, your AML status for a part will be set by the PLM and carried over into the PDX when exported. To set the AML status, you will need to modify the entry in your PLM.
If PDX is not available, BOM Advantage supports a Comma Separated Values (CSV) file (RFC 4182).
The BOM file consists of data about the hierarchical structure and item quantities in the BOM (Level, Item Number, Item Description, and Quantity) and the parts on the approved manufacturer’s list (AML) (Manufacturer Part Number, Manufacturer Name, and AML Status). You can either set the AML status by adding a column separately to the CSV inside a tool like Excel or it can be exported direcly by your PLM. It is recommended that you set the AML status in the PLM.
