Loadviewpoint and Loaddimensionviewpoint commands are not working

Hi,

We are trying to load a file into a viewpoint using epmautomate commands.

As per the oracle document

Commands at a Glance

the 2 possible commands are Loadviewpoint and Loaddimensionviewpoint.

We're facing issues with both the commands:

In loadViewpoint,

1. we're getting the error "EPMAT-7:"loadViewpoint" is not an epmautomate command. See "epmautomate help"." if we use the standard syntax i.e. epmautomate loadViewpoint VIEW VIEWPOINT PURPOSE FILE_NAME [loadType=ReplaceNodes|Merge]
2. Whereas when we replace the Purpose with a defined load name, the load is happening in merge mode
   1. We're not able to replace the nodes regardless of the command loadType or disabling/enabling the merge options in the defined load
