[SOLVED] Earned value calculation

Hello 
we need your help to calculate the earned value for our projects using projeqtoria :
according to my understanding the revised value is the new planned value ,  how to calculate  the earned value and what is the relationship with work margin and validated work.
Do you have a plan for integrating it into reports and integrate Estimated cost and end at complation. 
thanks and regads  

Thank you for your prompt reply ,
I m thinking that Earned value could be = total project validated value x technical progress it seems’ the most close to the definition of EV in project management concepts , I did calculations of EAC and SAC based on that and ithe results seems to be realistic and acceptable , is that correct ?

Is The ticket planned in the near future or it does not have a Fiix Ed end tile yet
