Your column is badly defined in the RPD. If the year (I assume it's a year column) doesn't have NULLs, don't define the relative physical column as nullable. The '.00' is maybe because it is defined as a different type than integer?
1.) Year should be an INTEGER. Not a DOUBLE.
2.) Does your column contain NULLs physically? I.e. in the database / data source?
OBI is an analytical tool. It's not there to hide bad data. Fix the data. Fix the model.
Thanks both of you,
Mr. Christian there is no option to mark your answer correct as I marked for Mr.Gianni but I am really thankful to both of you, You solved my problem
