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 Matching.
Actions taken based on the target schema are rendered as new steps in your recipe at the current location.
Target Matching Panel in Column Browser
In the Target Matching panel, a target schema that has been associated with your recipe is displayed as an extra set of columns on the left side:
|Left||Column from target|
|Right||Column from source (current recipe)|
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.
Tip: Mouse over tags that are not solid green to learn the nature of the column mismatch. You can then click the tag to insert steps in your recipe to match the two columns.
|Match by Name||Match by Data Type||Match by Position||Icon||Description|
|No||-||-||Square - red outline|
Target column has no identifiable name match in source. Column appears to be missing from source.
|Yes||No||No||Square - blue outline||Source column name has a matching target column name, but is in the incorrect location.|
|Yes||Yes||No||Square - green outline||Source column name and data type have a match in the target, but it is in a different position.|
