A/R Aging

[Walt Pennington]

I have A/R items that were generated manually and by producing an
invoice.  The manual entry is:

A/R    Client            $100
   Income:Client122            $100

When I age A/R, the only items that appear are those that were generated
using GnuCash's Invoicing system.

Can A/R be aged if you are not using the Invoicing?  If so, how do I
generate a report on the aging?

Thanks,
Walt
