CJE0 REPORT actual cost is inaccurate

Hi,

Working on customer projects.

We are booking the costs from MM flow and milestone billing through SD.   In the report, they are showing correctly.

But, When we are making FI entry through FB60 or F-02  posting to WBSE, in the report, system is deducting from the actual revenue and is not adding to actual cost. 

The costs should be added to actual cost in the report.

Any configuration is missing in this case or is it product error?

Please suggest for the same.

Thanks

Satya
