Cascading Data Sets can be created when Keyword Types are connected in a hierarchical parent/child relationship. Child Keyword Values in Cascading Data Sets are filtered based on the selected parent, or root, Keyword Value. Limiting the child Keyword Values that appear in a drop-down list expedites document retrieval and indexing. Cascading Data Sets can be applied to Document Types and Folder Types.
For example, a Document Type has three Keyword Types: State, County, and City that are configured as a Cascading Data Set. Selecting Ohio as the State Keyword Type filters the County Keyword Type drop-down list so that it only contains Keyword Values for counties that are in Ohio. Subsequently, selecting Cuyahoga as the County Keyword Value filters the City Keyword Type drop-down list so that it only contains values for cities in Cuyahoga County.
Before creating Cascading Data Sets, ensure that you are familiar with the following information:
-
Data from an existing Keyword Data Set cannot be migrated directly to a Cascading Data Set, but it can be used to populate a Cascading Data Set. For more information, see Using Existing Keyword Data Set Data to Populate a Cascading Data Set.
-
You can only add Alphanumeric, Numeric (Up to 9 Digits), or Numeric (Up to 20 Digits) Keyword Types to a Cascading Data Set.
-
Keyword Types that are part of a Cascading Data Set are displayed with a drop-down list, even if the Use Keyword Data Set and the Allow Drop-Down Lists settings have not been enabled for the Keyword Type.
-
Keyword Values for a Cascading Data Set Keyword Type located within a Multi-Instance Keyword Type Group can only determine available Keyword Values for other Cascading Data Set Keyword Types located within the same Multi-Instance Keyword Type Group (i.e., influence of Cascading Data Set Keyword Types within a Multi-Instance Keyword Type Group is limited to the confines of the Multi-Instance Keyword Type Group).
-
Keyword Types that are part of a Cascading Data Set respect the Keyword Select List User Option in the OnBase Client. To display Keyword Types that are part of a Cascading Data Set without drop-down lists, disable this option. When this option is disabled, users will not have access to drop-down lists. They will be required to manually enter Keyword Values for Keyword Types that are part of the Cascading Data Set. However, OnBase will continue to validate these manually entered Keyword Values against the Keyword Values in the Cascading Data Set. For example, a user indexes a document that contains State, County, and City Keyword Types. These Keyword Types are configured as a Cascading Data Set. The user cannot use drop-down lists to index this document because the Keyword Select List User Option is disabled. The user types Ohio as the State Keyword Value, Cuyahoga as the County Keyword Value, and New York City as the City Keyword Value. The user indexes the document. OnBase displays a message stating that New York City does not match the Cascading Data Set. The user is required to enter Keyword Values that appear in the Cascading Data Set before the document can be indexed successfully.
Cascading Data Sets are not supported for use with the following OnBase modules and functionality: HTML-based forms, E-Forms, Workflow User Forms, Workflow Filters, Custom Queries, Case Sensitive Keywords, and Reverse Keyset Lookup. When using these modules and functionality, OnBase ignores Cascading Data Sets and their associated Keyword Values are not available. If the Keyword Type in the Cascading Data Set was configured to use a Keyword Data Set, Keyword Values from this Keyword Data Set will be available. If the Keyword Type in the Cascading Data Set was not configured to use a Keyword Data Set, no Keyword Values will be available.
