[Vtigercrm-developers] Custom fields in reports (Invoice)

[Sajut Arhezov]

Hello to everybody,

Sajut here. Nice to meet you to everybody from this list.
I am an advanced user of VTiger and a rookie PHP programmer.

I've discovered last days that i need a custom report that includes Tax 
Percent and Tax Amount from Invoices in my custom report.
I am not able to check from standard reports and it seems that it 
require a piece of code.

Can you please provide me this piece of code and some references on how 
to do this for other fields (maybe custom fields that i am doing)?

I really appreciate your help.

Best regards,
Sajut.
