it is my first post here

I have the following problem. There is a turbo integrator process, which loads data in a cube.
There are 8 cubes very similar to this, in 2 cubes the load process works perfectly, but in the other 6 cubes, no way to load any data.
Turbo integrator finish the process successfully, but when I try to get the values, I get a message "no values available".
Does anyone has a clue, where my problem might be? I have include a screenshot of a dummy loads. Very simple, but no chances.
Many thanks in advance.
P.S.: I also tried with excel, no chances too.
