What are the federated search requirements for remote dataset?

[FritzWittwer]

I am trying to setup a federated index, on a federated search head, but i am only able to select an index as the remote dataset. the drop down for dataset type does not offer any other option. How do i have to configure the dataset on the remote search head in order to be able to use it on the federated search head.

Bot systems are clustered search heads running Splunk enterprise 8.2.2

Found the Answer, only indexes can be accessed with a federated search, see Create a federated index

Dataset Specification

Specify the Type of remote dataset that this federated index maps to and provide the Object Name for the dataset. Currently, only the Index dataset type is available. For Object Name you must provide the name of an index that currently exists on the selected federated provider.

The dataset Type defaults to Index. Object Name has no default.
