Variable with "Aggregation level" accesible in exit

Hi, experts¡

I have a problem with one of the relations we've implemented in our IP model. It's an exit one. Relations are defined for an appropiated infoprovider, but not for each aggregation level. I need to evaluate the aggregation level in the exit we've built for that relation, copied from CL_RSPLS_CR_EXIT_BASE and fixed with our own coding. Does anyone know any standard variable inside the class containing the code of the aggregation level??? If that's the case, i can evaluate it and decide whether to run the relation.

Thanks in advance.
