    // Read report Id from Model
    var embedReportId = "25f8b577-81fd-4769-8a3f-XXXXXXXX";

    // Get models. models contains enums that can be used.
    var models = window['powerbi-client'].models;

    // Embed configuration used to describe the what and how to embed.
    // This object is used when calling powerbi.embed.
    // This also includes settings and options such as filters.
    // You can find more information at https://github.com/Microsoft/PowerBI-JavaScript/wiki/Embed-Configuration-Details.



    var config = {
        type: 'report',
        tokenType: models.TokenType.Embed,
        accessToken: accessToken,
        embedUrl: embedUrl,
        id: embedReportId,
        pageView: "oneColumn",
        permissions: models.Permissions.All,        
        pageView: "oneColumn",
        settings: {
            filterPaneEnabled: true,
            navContentPaneEnabled: false
        }
    };

    var reportContainer = $('#reportContainer')[0];

    var report = powerbi.embed(reportContainer, config);

      var basicFilter = {
        $schema: "http://powerbi.com/product/schema#basic",
        target: {
            table: "M_Merchants",
            column: "Merchant_ID"
        },
        operator: 'In',
        values: "['119','120']",
        filterType: 0 
    };

    report.getFilters().then(function (allTargetFilters) {
        allTargetFilters.push(basicFilter);

        // Set filters
        // https://microsoft.github.io/PowerBI-JavaScript/interfaces/_src_ifilterable_.ifilterable.html#setfilters
        report.setFilters(allTargetFilters);
    });
