DisableStorage

The DisableStorage Property can be configured to True, indicating a Data item will not be read from or written to the configured storage.

The DisableStorage is usually configured for calculated data items, not to be stored, but configured in a Container for which a storage is configured.

The default value for this property is: False

on a case parameter of a template

A case parameter of a Template can carry the property, and since GeoDMS 20.19.3 the instantiated parameter carries it too. Before that, the property was lost on instantiation, because a case parameter takes its properties from the argument it is instantiated with: the parameter then took part in any storage of an ancestor of the instance, and an MMD writer stored a DisableStorage’d parameter unit as a domain of its own. The other properties of a case parameter still come from the argument.

below an MMD storage holder

An MMD storage treats everything below its holder as part of the store, so since GeoDMS 20.19.3 an item with DisableStorage = "True" below a holder that is being written makes the write fail, naming the item. Before that the item was silently left out of the dictionary, with attributes declared on it written against a domain the dictionary did not carry. See MMD for what to do instead.
