Hello Seniors!
I tried to merge the two datasets but returned with the message "variable ISIN does not uniquely identify observations in the master data". I am using ISIN as a unique identifier. My data is panel data of 10 years hence this ISIN would be keep repearting due to time series data.
I have checked the duplicated but retunred no more than 1 copy.
What could the possible error?would appreciate some input in this regard.
Thanks in advance.
