# Indented Bill of Material Listing (BOM.R3)
Read Time: 2 minute(s)
The BOM.R3 procedure is used to create indented bill of material listings. The user may specify each bill of material he would like to see by entering the part number which identifies it. The user may also enter any of the Parts file cross-reference items which include model number, category, and manufacturer part number. If these are entered the system will automatically substitute the corresponding part number, or display a list of possible part numbers which can be chosen.
The difference between this indented bill of material listing and a standard bill of material listing is that the indented listing shows not only the parts called out on the specified assembly, but also all of the parts called out on each sub-assembly referenced through all levels of the product structure. The report denotes the level of the part by placing one period (.) in front of the part number for each level.

Qty The quantity required of the part to make one unit of the assembly defined by the bill of material. Please note that the quantities shown for sub-assembly components have been multiplied by the quantity shown for that sub-assembly. This is done so the quantity will indicate the full amount required to make one unit of the top assembly rather than just one unit of the associated sub-assembly.
UM The unit of measure associated with the quantity.
