Hello,
i got the same error during activating the content cube 0IC_C03 and 2LIS_03_BF DataSource.
The problem was, that i just added a field to the 2LIS_03_BF_TR InfoSource and after that the transformation into the cube was inactive with that error.
The problem was the new field which was located at the "Possible Source Field" area.
Just push it to selected field an activate all the routines.
no need to change anything and no error after it ...
