How I can know the date of some aggregation?

Hi,

I am starting with aggregations and I have copy and standard aggregation wich adds the amount of transactions for the same RETAILSTOREID, MATERIAL and DATE.

The result of the aggregation is in the /POSDW/AGGR01 database but I can't know the date of the transaction. I have made two transactions with same data, but I have changed their dates. The database shows two entries but I can't know the bussinesdaydate of each transaction.

Thanks for your time.

Best Regards
