Totalizers

Totalizers are aggregate functions applied to table columns in order to obtain a unique value, which will shown at the bottom of the column.

They are only meant as a display option (storing the totalizer is not currently possible). To store the total value of a column please refer to: store the total value of a column using expressions.

 

These aggregate functions are:

 

Count: Returns the total number of records in a column (row count).

Max: Returns the largest value of a column.

Min: Returns the lowest value of a column.

Average : Returns the average (mean) for a column.

Sum: Returns the sum of values of a column.

In general totalizers apply only to numerical type columns (integer, float, currency, etc). Only the Count totalizer can be applied to any kind of column.

 

Totalizers are available in the Advanced tab of the columns properties.

Totalizer example

In a Purchase Request process, it is desired that the total price of all products requested is displayed at the bottom of the table.

In order to do this, we will apply an aggregated function to the Price column of the Products Requested table.

 

1. Go to the Activity Form and select the Products table; then click the Edit Columns button.
