Calculation Bar extension for SAP Analytics Cloud – Analytic Application

I recently fielded a customer request for an SAP Analytics Cloud implementation of the Excel status bar, where basic calculations show up for the current cell selection:


Status bar in Excel

This functionality isn’t currently available in the SAC table component, but I immediately thought of implementing it in an Analytic Application using the power of JavaScript. I’ll share the approach here in case it can be helpful to anyone else, along with some lessons I learned along the way.

Beginning with the end in mind, here is a snapshot of what we will build:


Calculation Bar you will have at the end

There are 7 calculations and the code only fires when data cells are selected. Let’s get started!

First, we will create an analytic application using the Best Run Juice sample model that comes with SAC.

  1. Click the menu icon, create, analytic application
  2. Add a table component, rename it to Table_Calc, and bind it to the model in Samples > BestRunJuice_SampleModel
  3. Add ‘Product’ to the row axis, and add all of the 5 measures to account on the column axis
  4. Enable ‘Show only Leaves in Widget’ for the Product dimension by modifying the hierarchy properties:
  5. Next, let’s disable scaling of measures so we can spot check our work in the end. This is for display purposes only, as the API we will use to get the values operates on the unformatted values. Select the table, click styling, and set Scale to ‘Unformatted’
  6. Apply a filter on Date = “Dec H2/2016” and Store = “Ozzy” just to keep the numbers under control.
  7. Create a Calculated Measure calculation called ‘Zero’ with a value of 0 to demonstrate the Average excluding 0 methodJust%20a%20placeholder
  8. Add a text box component, rename it to Calc_Bar, and uncheck the ‘Show this item at view time’ option. This keeps the calculation bar hidden until we have values to populate it with.
  9. Now we get to write some code! Modify the ‘On Select’ event of Table_Calc as follows:
    if (Table_Calc.getSelections().length > 1) {
    	var ar = Calc.getNumArray(Table_Calc.getSelections());
    	Calc.setStatusBar(ar, Calc_Bar);

    And just like that we’re done!

    Just kidding … most of the work comes in creating the Calc object and script functions, which we will tackle in a minute. All you need to know about this code block is that it won’t fire unless more than 1 cell is selected, and that the rest of the blog will focus on creating the ‘Calc’ script object and its functions.

  10. Let’s create the following object and functions:Using this structure (pro tip: max, min, and sum have the same structure. Create one and duplicate it for the others)
    Name Return Type Set as Array Arg 1 Arg 1 Type Arg 1 Set as Array Arg 2 Arg 2 Type
    getNumArray number YES sel Selection YES
    max number NO exec number YES
    min number NO exec number YES
    setStatusBar void NO ar number YES statusTextBoxName Text
    sum number NO exec number YES
  1. A few notes based on my experience up to this point. This structure could be refactored to do all of the calculations (max, min, sum) in a single function that returns an array with 3 (or 7) values. I left them separate here to keep everything modular.For the setStatusBar function, statusTextBoxName accepts a Text object so we don’t have to hardcode the name of the component in the function. It might be superfluous, but I wanted to keep the script functions generic wherever possible.
  2. Enter the following code for ‘getNumArray’:
    var ar = ArrayUtils.create(Type.number);
    	for(var i=0;i<sel.length;i++) {
    		var singleSel = sel[i];
    		if (Table_Calc.getDataSource().getData(singleSel)) {
    			if (Table_Calc.getDataSource().getData(singleSel).formattedValue !== "–") {
    return ar;

    This function parses the user selection in the table and pushes the raw (unformatted) values into a number array. It is the foundation for the rest of the functions. We loop through every cell in the selection, and if the value is a non-null number, include it in the returned array.

  3. Enter the following for ‘max’:
    var max = ArrayUtils.create(Type.number);
    for (var i=0;i<exec.length;i++) {
    	if (max.length === 0) {
    	if (exec[i]>max[0]) {
    return max[0];

    SAC provides the Math.max and Math.min methods, but they do not accept arrays … only 2 values. Proper JavaScript allows the syntax:


    But this doesn’t work in the analytic application designer. Hopefully the available JavaScript expands in future releases. For now, I wrote this function that pushes the first value in the number array and compares all the remaining values and updates the max accordingly.

  4. A minor change for the min function:
    var min = ArrayUtils.create(Type.number);
    for (var i=0;i<exec.length;i++) {
    	if (min.length === 0) {
    	if (exec[i]<min[0]) {
    return min[0]; 
  5. Next, the sum function:
    var sum = 0.0;
    for (var i=0;i<exec.length;i++) {
    	sum = sum + exec[i];
    return sum;

    We really want access to array.reduce() here but it isn’t available on the array object. Again, something I hope becomes available in the future.

  6. Finally, the setStatusBar function:
    if (ar.length>1) {
    var format1 = NumberFormat.create();
    var sum = Calc.sum(ar);
    var min = Calc.min(ar);
    var max = Calc.max(ar);
    var ar_ex0 = ArrayUtils.create(Type.number);
    for(var i=0;i<ar.length;i++){
    	if (ar[i] !== 0) {
    var sumText = "Average: " + format1.format(sum/ar.length) + " | " +
    			  " Average (Excluding 0): " + format1.format(sum/ar_ex0.length) + " | " +
    			  " Count: " + format1.format(ar.length) + " | " +
    			  " Sum: " + format1.format(sum) + " | " +
    			  " Min: " + format1.format(min) + " | " +
    			  " Max: " + format1.format(max) + " | " +
    			  " Range: " + format1.format(max - min);
    else {

    This is the longest function, where we do the calculations and update the text component with the results. We also apply a number format to prevent crazy floating-point precisions. I put the logic to calculate average without zeros here as well, though it could be refactored like the other calculations.


Now the final result:

I hope you find this SAP Analytics Cloud ‘Calculation Bar’ useful. Feel free to use it in your own projects and drop me a line in the comments if you have other ideas for analytic application extensions.

      Thanks Jim. This is an awesome extension for customers moving away from excel to the web.
