Integration Suite | Export | Posthandlers
If required, select from the available posthandlers to send data to an external storage, send referenced assets or validate files, for example.
In the “Filter” field, you can search for post-processor plug-ins. The list will be filtered based on your search term.

After saving the context, you have further setting options for each posthandler, e. g. the information of the target system.
You can select any number of target systems for each posthandler.
