Hi,

i had a similar issue and found out that depending on the mapping you need to set the supported datalength:

    "dataViewMappings": [
        {
            "table": {
                "rows": {
                    "select": [
                        {
                            "for": {
                                "in": "parameter"
                            }
                        },
                        {
                            "for": {
                                "in": "value"
                            }
                        }
                    ],
                    "dataReductionAlgorithm": {
                        "top": { "count": 5000000 }
                    }
                }, "rowCount": { "supported": {"max": 5000000}}
            }
        }

 

now i always get all rows since it will never exceed 5 mio 😉
