Function tree

The following code should work. Put it in a report and set the context of the report to the Function Tree model type. Output should be Excel.

var g_nLoc = Context.getSelectedLanguage();
var g_oOutfile = Context.createOutputObject();

// Define style
g_oOutfile.DefineF("Standard", "Arial", 11, Constants.C_BLACK, Constants.C_TRANSPARENT, Constants.FMT_LEFT, 0, 0, 0, 0, 0, 0);

function main()
{   
    var aoObjOccs = ArisData.getSelectedModels()[0].ObjOccList();
    if (aoObjOccs.length > 0) {
        // Determine root objects
        var aoRoots = [];
        for (var i=0; i<aoObjOccs.length; i++) {
            var oObjOcc = aoObjOccs[i];
            if (oObjOcc.InEdges(Constants.EDGES_ALL).length == 0)
                aoRoots.push(oObjOcc);
        }
        // Determine table width and write header (10 columns hardcoded)
        var anColumns = [];
        for (var i=0; i<10; i++)
            anColumns.push(10.0);
        g_oOutfile.BeginTable(100, anColumns, Constants.C_BLACK, Constants.C_TRANSPARENT, Constants.FMT_LEFT, 0);
        g_oOutfile.TableRow();
        for (var i=1; i<=10; i++)
            g_oOutfile.TableCellF("Level "+i, 1, 1, "Standard");
        g_oOutfile.TableRow();
        // Write out the tree data
        for (var i=0; i<aoRoots.length; i++) {
            writeTree(aoRoots[i], 1, i>0);
        }
    }
    g_oOutfile.EndTable("", 100, "Arial", 11, Constants.C_BLACK, Constants.C_TRANSPARENT, 0, Constants.FMT_LEFT, 0);
    g_oOutfile.WriteReport();
}

function writeTree(p_oRoot, p_nLevel, p_bNewlineAndIndent) {
    if (p_bNewlineAndIndent) {
        g_oOutfile.TableRow();
        for (var i=1; i<p_nLevel; i++)
            g_oOutfile.TableCellF("", 1, 1, "Standard");
    }
    // Insert the root's name
    g_oOutfile.TableCellF(p_oRoot.getObjDefName(-1), 1, 1, "Standard");
    // Get and insert the root's children
    var aoChildren = p_oRoot.getConnectedObjOccs(null, Constants.EDGES_OUT);
    for (var i=0; i<aoChildren.length; i++) {
        writeTree(aoChildren[i], p_nLevel+1, i>0);
    }
}

main();
