there are 4 user custom fields, you could try

for placing the UPC # in the description#3 line you may have to use a period or underscore to occupy the line 2

I use the custom fields in maintain customers, but when I went to maintain parts but I don't see custom fields. Am I missing it - I looked everywhere.  I see 5 for categories though.

yeah that's what I was thinking,

1. you can rename them in IC - > Utilities-> IC Parameters

2. Make sure before you commit to using a "field" for re-purposing,  the data can be seen where you want to use it.  i.e.  on an invoice or SO or PO or packing list

I use the SAMPLE / DEMO companies for this

thanks. categories did not work for me because it takes only 10 characters - our UPC codes r 12.  just landed up putting it in description line 2 since we don't use it.  thanks for your help.

Good workaround.
