Import not Copy:-

While deploying a mapping from Dev to QA or QA to Prod,always try to import first.
If you face any error in importing then copy the mapping from source to target environment.
The reason for that is while copying the sources and targets gets copied as NON-SHORTCUT whereas they should have been copied as shortcut.

There might be possibility that in your project you keep all your source/target/transformation/mapplets etc into a shared folder and you are using those components in different different mappings.

In copying they will be copied not as shortcut to that folder but a separate copy which definitely you dont want.
