InfoObject 0CONTCOST (version A) is not compounded

Hello experts...

I am getting the above error message when trying to load into cube 0PC_C01 CO-PC: Cost Object Controlling. I get the same message with either of the two DTP that go into the mentioned target. the field 0CONTCOST is a key figure therefore is not compounded... I don't understand what is going on... Anyone has an idea of the meaning of the error I am getting..

Thank you in advance
