Adding new fields to a managed entity
Users can add a new field to a managed entity. Multiple fields can be added one at a time.
In the source module, users first select the entity to append the field to. Note that fields will only be appended to the end of entities and fields screen must be accessed from the entity grid by selecting (View Fields) icon from the parent entity. See Properties Impacted by Schema Evolution By Source below for information on properties that will be affected by this schema change.
Additions and deletions to fields in Mainframe entities are not supported. Metadata definitions for COBOL Mainframe entities must be declared through COBOL copybooks.
In fields tab, select Add Fieldbutton
Review: For this example field Name 'LEVEL' and external Data Type 'CHAR'; the application retains the Field Name and maps to internal Data Type (over-writable via dropdown).
Confirm screen details the associated dataflows and user views that will be invalidated by this change if any exist.
The entity has been updated with new field metadata and is ready for ingest of those field values. The same entity and the new field can be viewed in discover now displaying the internal data type.
