CO tables COEJ and COSP with different total

Hi,

I am wondering why I have a difference in total amount between table COEJ and COSP.

I have selected on both for a specific wbs-element and value type 1 and Version 1.

I left the year empty.

In COSP I have values for 2014 and 2015.

In COEJ I have only values from 2014.

The total sum for 2014 is equal in both tables. But for 2015 I have only values in COSP and nothing in COEJ.

What could be the reason, that I have no values from 2015 in COEJ ?

Thank you very much for your Support.

Best regards
