Location of Email field in Agent Object

Hi,
Im trying to find a field which I can use to store additional info about an agent (sales system ID) that I can query from the config DB. I believe that the additional fields within the CFG_PERSON table in config database cant be populated from within CME. Therefore the only field I can see where I can add freetyped text and that isnt being used is the e-mail field. the problem is that when I populate that field on an agent object, I cant see where that entry is stored in config DB. There is no field for it in the CFG_PERSON table and Ive been through all tables and cant find it anywhere??
Any ideas?

???

have you thought of using the employee id field?

Hi Scotty,

And what about Annex tab? Have you considered this option? You can create as many additional option fields as you need.
Then you can find them in table cfg_flex_prop.

Cheers,
