Is it possible to have numeric fields passed onto `$filter`?
It is necessary to filter based on IDs.
So far, I've been unsuccessful. If I use quotes around a value, e.g. `$filter=FieldDetails/FieldId%20eq%20'6'`, then I would see an error in Power BI saying that the field is invalid. If I don't surround a value with single quotes, then there will be no filtering at all.
I've certainly marked the field as a visible one in my .pbix.
