How to Merge Polymorphic Attribute Versions

This feature allows you to automatically merge all numeric attributes into either the float or string polymorphic version of the attribute by creating a sql expression and an alias.

This is useful when you have multiple numeric attributes that represent the same data but in different data types (e.g., str, int, and float).

On the Pipeline Designer, select your data source and click on the Transformation/Security tab

Open the merge polymorphic versions section

Note: This operation sets INCLUDE_IN_SEMANTIC_LAYER to TRUE for the polymorphic version (string or float) that is being merged into, and to FALSE for all other polymorphic versions.

Select string in the dropdown to merge numeric attributes into string polymorphic versions

Click "Merge Attributes"

Select float in the dropdown to merge numeric attributes into the float polymorphic version

Click "Merge Attributes"
