You can copy segments of mappings and mapplets when you want to reuse a portion of the mapping logic. A segment consists of one of more objects in a mapping or mapplet. The objects can be sources, targets, shortcuts, transformations, and mapplets. To copy mapping segments, select and copy the segments from one mapping and paste them into a target mapping. You can paste segments of mappings or mapplets into an empty mapping or mapplet workspace. You can also copy segments across folders or repositories.
