MDXView: Support additional body properties (e.g., Meta, IsAutocalculate)

[151N3]

Feature Request

Currently MDXView.construct_body() only serializes @odata.type, Name, and MDX. The TM1 REST API accepts additional properties on MDX views, most notably Meta, which enables powerful PAW/Planning Analytics Workspace features such as:

• Meta.Aliases — display members using a specific alias instead of the element name
• Meta.ContextSets — define subsets or expressions for context (title/WHERE) dimensions
• Meta.ExpandAboves — control expand-above behaviour per dimension

Without access to these properties from TM1py, these settings can only be configured interactively inside PAW and cannot be managed programmatically or via automation pipelines.

Proposed Change

Add an optional properties: dict parameter to MDXView.__init__() and include it in construct_body():

def __init__(self, cube_name: str, view_name: str, MDX: str, properties: Optional[Dict] = None):
    ...
    self._properties = properties or {}

def construct_body(self) -> str:
    mdx_view_as_dict = collections.OrderedDict()
    mdx_view_as_dict["@odata.type"] = "ibm.tm1.api.v1.MDXView"
    mdx_view_as_dict["Name"] = self._name
    mdx_view_as_dict["MDX"] = self._mdx
    mdx_view_as_dict.update(self._properties)
    return json.dumps(mdx_view_as_dict, ensure_ascii=False)

Example Usage

view = MDXView(
    cube_name="EIS_CUBE",
    view_name="Dummy_View",
    MDX="SELECT ... FROM [EIS_CUBE] WHERE (...)",
    properties={
        "IsAutocalculate": False,
        "Meta": {
            "Aliases": {"[dim_One].[dim_One]": "Short_DE"},
            "ContextSets": {
                "[dim_Four].[dim_Four]": {"IsPublic": True, "SubsetName": "Default"},
                "[dim_Three].[dim_Three]": {"Expression": "{[dim_Three].[dim_Three].MEMBERS}"}
            },
            "ExpandAboves": {
                "[dim_Four].[dim_Four]": False,
                "[dim_Two].[dim_Two]": False
            }
        }
    }
)
