Fusion Univers Bo avec Excel double dimension

Good evening, I appeal to you on a subject of fusion between objects of the universe and an Excel source.
On the BO universe side, I also have a DIM0 dimension type object, another DIM1 and another DIM2 information type object. On the other side I have a second Excel source with another dimension DIM1 and another DIM2. The values ​​of DIM1 and DIM2 objects are of the same format. The particularity is that the DIM2 object of the universe is of the Information type and not a dimension.
When I try to merge the 2 objects DIM1 and DIM2, the expected result is not as I wish.
Here is an example :
→ BO source
DIM1 = A1 A1 A1 A3 A3
DIM2 = B1 B1 B3 B1 B2
DIM0 = toto tutu titi tata ruru
→ EXCEL source
DIM1 = A1 A1 A3
DIM2 = B1 B2 B1
** Expected result :

from the common values ​​of DIM1 and DIM2 display the values ​​of dimension 0
DIM1 = A1 A1 A3
DIM2 = B1 B1 B1
DIM0 = toto tutu tata
=> the other dimensions are not common
