Description:
|
Depending on the nature and quality of available source, the state of the data collection/update process, and other conditions, it may not be possible to populate a value due to lack of knowledge. The reasons for the lack of a value may include, but are not limited to, the following: not populated (for example: the data store has been initialized but not yet populated); unknown (for example: an attempt was made to determine the value but the source materials were inadequate); missing (for example: a determination was attempted and despite source materials being adequate the attempt failed); withheld (for example: a determination was successful but for policy reasons the value was not retained/stored).
