Data Manager - NULL value
Assets Data Manager is included in all Service Collection Premium and Enterprise plans.
A NULL value (represented in in Data Manager by (NullValue) or (NULL) is a placeholder value in Data Manager that occurs when an attribute does not contain any data from a data source.
There are three possible reasons that a NULL value might occur:
The data sources does not contain this attribute at all.
The data source has not returned a value for this attribute.
The last updated value from this data source is stale (older than the period specified in the Refresh gap).
If a NULL value is imported into Assets from Data Manager, you can choose if the existing value should remain unchanged, be removed, or be updated to a literal NULL value in Assets (an empty string).
