But How!!!
In MSSQL side is type "Date" and in Report side is type "Date" too.
I create different DB in MSSQL and I created test table with date type and I got it same situation
Does CR create some where its own dataset?
I did Show Field Type in CR, Database Field and I really shocked !! The fields has been converted to String!! Why
So, My conclusion the Dataset (CR Database Fields) that created by CR is being converted. I do not know why and how to fix this situation
