I also got same error message when I create project forecast. Please advise.

This setup is already done.

• Create Cost/Revenue Elements.
• Maintain Cost/Revenue Element per Code Part Value.

@NecPattrC @mehdi.chouachoua you need to make sure that the Cost Element is defined in the below screen also:

Hi, thanks for the message.

My cost element is defined in the give screen, and i still receive the same error? 

Actually, I have defined it. 

I still got the error message.

Pls recheck at your Project Setup Parameter > PCE Code Parts

If we add some new cost element basic data after project creation, then we have to do manually add it into our project.

Now, my operation is worked for copying project forecast.
