Units:	-
Default Value:	0
Validation Rule:	In (0,1,2)
Description:	Method used to fill missing values when reading Data Files
Detail:

The article Text File Formats describes the many formats allowed for text file input data. Some of those formats allow values to be missing. Often this is used to compress input by removing values that repeat. The Data File attribute Missing Value Method controls how those missing values are treated:

Last Value (default, value = 0)

The last read value (in date order) is used to fill forward missing values. If no 'last' value is found in the file, then the 'next' value (in date order) is carried back to fill the missing values.

Zero (value = 1)

Missing values are substituted with zeros.

Default (value = 2)

Missing values are substituted with the default value of the property being read from the file.
