We are uploading safety stock using FBDI . Safety Stock method = safety stock quantity.

Which table are these uploaded values stored? We can find the uploaded safety stock in the planning collection table msc_st_safety_Stock but the main table msc_safety_stock has no data in it so which table do we find the safety stock in .

Also the collection table msc_st_safety_Stock stores old values also and we have to search for records with max refresh_number indicating the last SS upload. Why does this table store old data also?
