Error in moveDimension within a forEach for Swapping charts

Question

Hi All,
I tried to implement what was done in the following blog (which is a great idea) but it works perfect if I don't change the layout of any of the chart, mainly the bigger chart.
Blog: SAP Design Studio Tips and Tricks #1: Swapping charts into focus on-demand
In my case, what I see in the bigger chart could change.
For example, by default I see Sales by Region (Europe, America, Asia, etc), and the user can filter by a Region and see the Countries.
So, When I change the bigger chart with other chart I loose the filter and the drill down done before.
To solve this, I tried to "save" the drills made in rows and columns, before to do what it is done in the blog, but I don't know why the moveDimension is not working as I expected, what is more, when I execute the dashboard and run the event, it says there is an error in my script and the error is in the moveDimension.
I want to share my code, just if you have the chance to test it, and see if it works.
Thanks, Federico
My Code:
// Initializing variables
var DS1_Name = DS_1.getInfo().queryTechnicalName;
var DS2_Name = DS_2.getInfo().queryTechnicalName;
var system = DS_1.getInfo().system;
var chart = CHART_1.getChartType();
// Saving the layout
var DS1_COL_BEF = DS_2.getDimensions(Axis.COLUMNS);
var DS1_ROW_BEF = DS_2.getDimensions(Axis.ROWS);
var DS2_COL_BEF = DS_1.getDimensions(Axis.COLUMNS);
var DS2_ROW_BEF = DS_1.getDimensions(Axis.ROWS);
// Swapping charts
DS_1.assignDataSource(system, DataSourceType.QUERY, DS2_Name);
DS_2.assignDataSource(system, DataSourceType.QUERY, DS1_Name);
CHART_1.setChartType(CHART_2.getChartType());
CHART_2.setChartType(chart);
// Taking the actual columns & rows
var DS1_COL_AFT = DS_1.getDimensions(Axis.COLUMNS);
var DS1_ROW_AFT = DS_1.getDimensions(Axis.ROWS);
var DS2_COL_AFT = DS_2.getDimensions(Axis.COLUMNS);
var DS2_ROW_AFT = DS_2.getDimensions(Axis.ROWS);
// Removing dimensions
DS1_COL_AFT.forEach(function(element, index) {
  DS_1.removeDimension(element);
DS1_ROW_AFT.forEach(function(element, index) {
  DS_1.removeDimension(element);
DS2_COL_AFT.forEach(function(element, index) {
  DS_2.removeDimension(element);
DS2_ROW_AFT.forEach(function(element, index) {
  DS_2.removeDimension(element);
// Adjusting the charts as they were
DS1_COL_BEF.forEach(function(element, index) {
  DS_1.moveDimensionToColumns(element);
DS1_ROW_BEF.forEach(function(element, index) {
  DS_1.moveDimensionToRows(element);
DS2_COL_BEF.forEach(function(element, index) {
  DS_2.moveDimensionToColumns(element);
DS2_ROW_BEF.forEach(function(element, index) {
  DS_2.moveDimensionToRows(element);

Hi Federico Galban ,
I tried a similar scenario like this for  a much simple case the moveDimension part works fine for me.
I have a doubt in your script,
// Adjusting the charts as they were
DS1_COL_BEF.forEach(function(element, index) {
  DS_1.moveDimensionToColumns(element);
DS1_ROW_BEF.forEach(function(element, index) {
  DS_1.moveDimensionToRows(element);
DS2_COL_BEF.forEach(function(element, index) {
  DS_2.moveDimensionToColumns(element);
DS2_ROW_BEF.forEach(function(element, index) {
  DS_2.moveDimensionToRows(element);
Your goal is ultimately to swap the charts, so shouldnt this be done as follows
// Adjusting the charts as they were
DS1_COL_BEF.forEach(function(element, index) {
  DS_2.moveDimensionToColumns(element);
DS1_ROW_BEF.forEach(function(element, index) {
  DS_2.moveDimensionToRows(element);
DS2_COL_BEF.forEach(function(element, index) {
  DS_1.moveDimensionToColumns(element);
DS2_ROW_BEF.forEach(function(element, index) {
  DS_1.moveDimensionToRows(element);
Just asking to be clear, if wrong pls ignore
