To add a block template to your scenario, first select it from the Catalogs tab. Open the folder it is in, select the block you want, and if there is more than one version, select the version you want. The recommendation is to use the most recent version, which is implemented in a way that delivers better performance than the older version. Also, the most recent version is parallel-aware. Older versions will be removed in a future release.

As implied, it is possible to add multiple instances of the same block to the scenario. These will be named sequentially to differentiate between them. The unique naming of each instance is important, as all block instance feeds, fields, parameters, and operations are referred to from within rules by the enclosing block instance’s name.
