Lost data after modifying he data column names

Hello! I hope you’re having a great day.

Unfortunately, I made the mistake of modifying the data column names after the data collectors had already submitted the data. As a result, I ended up losing the entire dataset. Is there any possibility of receiving assistance in recovering the lost data? Your support would be immensely appreciated. Thank you kindly.

@nourkor, could you be more specific about what is missing? Did you mean the entire variable or the dataset?

If the dataset, could you be more specific with the steps you performed?

@Kal_Lam it is the data set.
I changed the column names i.e. column name was “sex_of_the_patient” but I changed as “sex” and data were already submitted then all dataset were missed except certain variables where I didn’t change it is column name but variables are available
