ORACLE to SQL Migration error on converting datatype

Hi,

I hope someone could help me to get around this. I am migrating the ORACLE data to SQL server using SSMA. When I execute the Migrate data I got an error below

The given value of type DateTime from the data source cannot be converted to type int of the specified target column.
 Errors: The given value of type DateTime from the data source cannot be converted to type int of the specified target column.

I checked all the columns they look like it's mapping correctly and I am not sure what caused it and how to get around it.

Thanks
