Revenue Values in Cost element category '11'

Hi,

We have revenue GL for which I miised to make the Cost eleemtn category '11'.

As a result for few Sales Order and related billing the data did not flow to COPA. Now , I have made it as cost element , so that data is coming perfectly.

My my question, can I get the revenue data that I have miissed for the billing data.

Any help

Regards
