Create Transformation

After you have registered the extractor and stored the client credentials, you can get started with data transformation.
After you have uploaded the data to the CDF project, you need to create a transformation in CDF.
Perform the following steps to create transformation:
  1. Navigate to your project in CDF and select
    Integrate
     >
    Transformations
    .
    Select Transform Data
  2. On the Transformations screen, click
    + Create transformation
    .
    Select Create
  3. Provide a unique name for the transformation.
    Create Transformation
  4. Provide a unique external ID.
  5. Select a data set to limit access to the selected data set and click
    Next Step
    .
  6. In the
    Target data model
     list, select
    CDF resource types
     to ingest data.
    • If you are ingesting data into the assets resource type, make sure a parent asset already exists in CDF.
    • If you are ingesting data into Sequence rows, specify the external ID for the sequence you want to write to. This defines the target schema.

  7. In the
    Target resource type
     list, select
    Assets
    .
  8. In the
    Action
     list, select
    Create or Update
    . If you are updating existing data, you must specify how the transformation should set null values.
    • Select
      Keep existing values
       to not update existing data. This is the default setting.
    • Select
      Clear existing values
       to set existing values to null, for example, when a piece of equipment is removed for maintenance. Use this option to disassociate the asset from its parent in the asset hierarchy.
  9. Click
    Create
     to create the transformation. After you create a transformation, you need to select a source for data transformation.
    The
    Mapping editor
     is displayed. Mapping editor helps mapping source and target.
