I'm using the SSIS package, there is nothing being changed from source to destination. However, the column which I'm paying attention right now has a slightly different datatype (which I hope doesn't matter) in the source and destination; the source has numeric (15,2) and the destination has numeric (16,2) and the data in the source is 4.75 and it changes to 5.
The 1 digit reduction in the decimal places, which I'm sure, should not matter because I tested with the case.
Why is the value rounded?
