Exclude all zero data from MALO extract to BW

Question: We are extracting data from the SNP MALO aggregate and loading the data to a BW infocube. We are using the new CHANGE_SELECTION BADI to select the material/location combinations that we want to extract data for.

Does anyone know of a way to determine if all the key figures for the entire planning area time horizon are zero for a material/location combination? I would like to exclude these materials/locations from the transfer to BW. The reduction in records would improve both the BW loadtime to the infocube and the execution of the BW queries.
Thanks.
Ryan
