I am getting an error while creating a data schema. Below is the error message:
SOP-330323 An error occured during the SOAP call. You don't have required rights to view the detail.
In addition to checking the admin rights, you can also check the web logs that gets generated while you try to create the schema.
But it does seem you are lacking the rights either admin or access to a folder for data schemas.
Do you have admin permissions? You need to have admin level permissions in order to save a schema.
