I have an Excel sheet created in MS Excel 2013. There are columns related to the days in a month. So if the sheet created is created for October, i have 31 columns in which daily data are entered datewise.
I want to put a restriction for users on the columns. The restriction will be once data for October 1st is entered then those data will be locked and cannot be modified once the day is over. The same day user can modify the data but once day is over then it should not allow to modify in the columns whose dates are already passed.
Need urgent solution..
