Why does the SilkTest error "Numeric field overflow" occur in DB_FetchNext when testing Excel?
This error is due to Excel rather than SilkTest. The cause is that Excel considers the format of each cell from its second row. If the first item of the second row is a number, it considers that the rest should be numbers.
There is no problem with this in Excel but once another application interacts with Excel to query the cell value, the problem arises. If say the third row is not a number, you will get the error message Numeric field overflow.
This issue can be overcome by modifying all the cells to place a single quote in front of every cell value.
