webMethods OneData provides features for mapping related entities. For example, you can map a relationship between standard codes and system-specific codes. Through the Linkages menu, you can map data and export mapping grids to Excel. You can also create a linkages column along with a multi-select construct.

For more information on multi-select configuration and viewing linkages, see Implementing webMethods OneData.

webMethods OneData supports temporal constructs in linkages.
