Introduction
This section provides an overview of how the recipe language can be used when exporting a package from the source PLM system. Recipe files are useful for specifying a complex collection and when the same criteria are used multiple times. A recipe file must be used to create an incremental or synchronization package.
See Exporting Packages for information concerning the preparation and basic package export, the command line utility, and troubleshooting tips for conflicts that you might encounter while exporting a package from the source PLM system.
