Error in hierarchy of the dimension time

Hiii!!!!

I have a problem that i don't know how i can solve with the dimension TIME. I would like show TIME.TOTAL This is because I need add the measure (Kg) (all year data) and show in one column  For exemple the next column structure.

When I want show the next COLUMN:

REAL

2015.TOTAL

KG

The report takes a long time to refresh and it gives error message. If I select only one month, the column goes well and show all data correctly. The issue is when i try to show in the report TIME.TOTAL column.

The error message is the next:

How I can solve this error?? All other time dimensión data works well, it only fails when I use the hierarchy

Thanks so much in advance
