Target Schema Mapping

You can associate a target schema with a recipe. A target schema is information about the column names, data types, and order of the target dataset for which you are trying to build your recipe. For more information, see Overview of Target Schema Mapping.

Actions taken based on the target schema are rendered as a new step in the location in your recipe.

Figure: Target Schema Mapping Panel in Column Browser

In the Target Schema Mapping panel, the columns of the target schema assigned to your recipe are displayed on the left side. Columns are listed side-by-side in order:

Side	Description
Left	Target column
Right	Source column (current recipe)

Schema Tags:

Between the two sets of fields are a set of tags that describe the matching between the two columns in the order listed in each dataset. Each tag describes the match found for the corresponding target or source column.

Matches by position are arrows.
Matches by data type are green in color.
Partial name matches are indicated by the color purple. In the cases, the platform has found a match when column names are inexact matches.
Red color indicates no match at all.

Mouse over tags that are not solid green to learn the nature of the column mismatch. You can then click the tag to match the two columns.

Match by Name	Match by Data Type	Match by Position	Icon	Description
