Looking for the missing taxes

[Hugh Esco <..hidden..>]

I have a test set of accounts.

They have a single part, and three assemblies made up of those parts.  

Both the part and each of the assemblies include:
     Tax X 2150--Sales Tax  
in their configuration.

For each of these items this table reads:

ymd_lsmb=# select * from partstax;
 parts_id | chart_id | taxcategory_id
----------+----------+----------------
    10121 |    10103 |

When I create a sales order, the oe table includes: 
amount $104.95, netamount $99.95.

But, the tax is not reflected in the browser on either the sales order
or on the invoice.  What might it be that I am missing here?
