The above data is loaded to QlikView memory by using the script editor. Open the Script editor from the File menu or press Control+E. Choose the Table Files option from for the file containing the above data. Edit the load script to add the following code. Click OK and click Control+R to load the data into QlikView’s memory.

LOAD Month,

     [Sales Volume],

     peek('Sales Volume') as Prevmonth

FROM

[C:\Qlikview\data\monthly_sales.csv]

(txt, codepage is 1252, embedded labels, delimiter is ',', msq);

Creating Sheet Object

Let us create a Table Box sheet object to show the data generated by the above script. Go to the menu item Layout → New Sheet Object → Table Box. The following window appears in which we mention the Title of the table and select the required fields to be displayed. Clicking OK displays the data from the csv file in the QlikView Table Box as shown below. Also set the sort order as shown below to get the result in the same order of the field Month as it is in the source.

On completing the above steps and clicking Finish, we get the Table box showing the data as given below.

Using peek() Function in Calculations

The peek() can be used in calculations involving other columns. Let us display the percentage change for sales volume for each month. The following script achieves this result.

LOAD

Month, [Sales Volume],

peek(‘Sales Volume’) as Prevvolume,

(([Sales Volume]-peek(‘Sales Volume’)))/peek(‘Sales Volume’)*100 as Difference

FROM

[C:\Qlikview\data\monthly_sales.csv]

(txt, codepage is 1252, embedded labels, delimiter is ‘,’, msq);

Creating Sheet Object

QlikView – RangeSum Function

The RangeSum() function in QlikView is used to do a selective sum on chosen fields which is not easily achieved by the sum function. It can take expressions containing other functions as its arguments and return the sum of those expressions.

Input Data

Let us consider the monthly sales figure as shown below. Save the data with file name monthly_sales.csv.

Month,Sales Volume

March,2145

April,2458

May,1245

June,5124

July,7421

August,2584

September,5314

October,7846

November,6532

December,4625

January,8547

February,3265

Load Script

The above data is loaded to QlikView memory by using the script editor. Open the Script editor from the File menu or press Control+E. Choose the Table Files option from the Data from Files tab and browse for the file containing the above data. Edit the load script to add the following code. Click OK and click Control+R to load the data into QlikView’s memory.

LOAD

Month, [Sales Volume]

FROM

[C:\Qlikview\data\monthly_sales.csv]

(txt, codepage is 1252, embedded labels, delimiter is ',', msq);

Applying RangeSum() Function

With the above data loaded into QlikView’s memory, we edit the script to add a new column, which will give a rolling sum of the month wise sales volume. For this, we also take the help of the peek function discussed in the earlier chapter to hold the value of the previous record and add it to the sales volume of the current record. The following script achieves the result.

LOAD

Month, [Sales Volume],

rangesum([Sales Volume],peek('Rolling')) as Rolling

FROM

[C:\Qlikview\data\monthly_sales.csv]

(txt, codepage is 1252, embedded labels, delimiter is ',', msq);

Creating Sheet Object

Let us create a Table Box sheet object to show the data generated by the above given script. Go to the menu Layout → New Sheet Object → Table Box.

The following window appears in which we mention the Title of the table and select the required fields to be displayed. Clicking OK displays the data from the CSV file in the QlikView Table Box as shown below.
