I am trying to understand few things about HANA SDA.
1. Firstly if we try to use HANA Smart data access for real time reporting how much load will the fetching of data put on the source SAP systems ? The reason being our SAP system is vigorously used during morning hours for production and any extra load on the system might cause delay in the production process. So we have to be very careful.
2.Secondly to be able to use Smart Data Access what is the lowest SAP ECC 6 service pack supported or does it matter at all cause we would be accessing the database directly ?
