I recieved a formula to big error. It did reference fields which also are a formula. I need to do the following... what is my best options using the customizing features. I just started to customize and add records about a week ago.
All the following fields are custom added fields.

I am attempting to do the following to get a percentage:
(A1+A2+A3+A4+A5+A6)/(A1+A2+A3+A4+A5+A6+B1+B2+B3+B4+B5+B6+C1+C2+C3+C4+C5+C6+D1+D2+D3+D4+D5+D6)

I got formula too big error!

I added additional custom fields sum multiple fields:
AT=A1+A2+A3+A4+A5+A6
BT=B1+B2+B3+B4+B5+B6
CT=C1+C2+C3+C4+C5+C6
DT=D1+D2+D3+D4+D5+D6

Then using
AT/(AT+Bt+CT+DT)

I Still get Formula too big error!

Is there a simple work around or a possible update to support more fields?
