Hi
I am explaining you the correct requirement is i am having 18 columns in a excel sheet with production server i have to take that file and do some calculations and put in 2 different tables and maintain the history. How can i achieve this but these all will done in backend server......
But in that sheet a column named as GUID but it will be duplicating(same GUID for all locations in that state i mean a state having one GUID but the locations in the state is having the same GUID) how can i split that 18 columns to 8 for one table and 14 columns to other table by adding calculations.
How can i achieve this what is the best approach i have to add a new identity column if i added that column and what basis i need to split that columns from the sheet.
