+.TH bom "" "" "/act/opr Command"
+.PC "Produce bill-of-materials from parts list"
+.B bom
+.PP
+.II "bill of materials"
+The command
+.B bom
+is part of the accounting/operations system included with
+.BR /rdb .
+It creates a bill-of-materials table from table
+.BR part ,
+which holds all of the items that are required to make a product,
+and the table
+.BR saleitem ,
+which holds all sales items from the sales department.
+This tells how many items must be manufactured or purchased
+to meet current sales orders.
+.PP
+.B bom
+writes its output into table
+.BR bom .
+.SH Example
+Assume the table
+.B saleitem
+contains the following data:
+.DM
+Order Number Code Backord Qty Price    Total Name
+----- ------ ---- ------- --- -----  ------- ----
+   1    1     rdb      10   1  1500  1500.00 /rdb 
+   2    1     rdb      10   2  1500  3000.00 /rdb 
+   3    1     rdb      10   5  1500  7500.00 /rdb 
+   3    2     act      10  10  1500 15000.00 /act 
+   4    1     rdb      10   5  1500  7500.00 /rdb 
+   4    2     rdb      10  19  1500 28500.00 /rdb 
+   5    1     rdb      10   5  1500  7500.00 /rdb 
+   5    2     act      10   9  1500 13500.00 /act

+Assume, too, that the table
+.B part
+contains the following
+data:
+.DM
+Code    Subpart Count
+------- ------- -------
+act     binder  2
+act     actdoc  2
+act     f1      10
+rdb     binder  2
+rdb     rdbdoc  2
+rdb     f1      10
+.DE
+.PP
+The command
+.B bom
+reads these tables to produce the following summary table:
+.DM
+Code    Qty
+------- -------
+actdoc       38
+binder      112
+f1          560
+rdbdoc       74
+.DE
+.PP
+You can see that we have orders for 19 copies of
+.BR act s
+in the
+.B salesitem
+table.
+Each package has two documents, for a total of 38
+.BR actdoc s.
+Note that table
+.B bom
+lists 560 floppies ((19 act x 10) + (37 rdb x 10)).
+We can order these, regardless
+of which software packages are being put onto them.
