Hi Alex,
What exactely do you want to do ?
I did add some phone number and billing system information on our OTRS
customer_user.
I changed the customer_user table added some columns.
Then you need to change the Config.pm.
Then I realized that the phone view customer lookup slowed down (I have
some 800.000 customers)so we added some indexes on the same table and
changed DB.pm files and Config.pm.
Speed is fine now; really faaaaast.
Plus developped a little perl script to updat the data fom our billing
system during the night.
I posted a low level howto on otrs earlier this year.
If this what you are looking for, try the archive. If you do not find it
there I can resubmit.
