This dialog allows you to match data between <units> if the plant hierarchy level you have selected is higher than <unit>.
Target
Select the required row of the <unit> you want to be the target.
Source
Drag the selected target <unit> and drop it on the source. The target <unit> name appears in the Connected To column.
Match Names
Matches source <units> to target <units> that have the same names. This option is useful for example, for quick mapping of the source and target <units> when you have a large number of <units> with the same names in the source and target projects.
Clear
Clears all the target <units> mapped to the source data.
