Changing the Display of Numeric Values
You are able to determine how a numeric value from the internal data table is to be displayed in the ALV output. To do this, you can use the following properties:
-
Number of decimal places
-
Unit of measurement
-
Currency
-
Rounding
With each of these properties, you either move the decimal point the desired number of places (thus changing the value of the number) or you change the number of decimal places after the decimal point (the value of the number then stays the same). You are also able to combine two or more options.
You are able to apply each of the properties in two ways:
-
You assign the desired property with a specific value to the column that contains the values to be displayed. Each of the values in the column is changed and displayed in the same way.
-
You use a separate column that applies the desired property to individual rows of the ALV output. For more information, see Columns with Special Technical Significance, in the section called Control Columns That Are Assigned to a Column.
You are able to make the following settings for numeric columns:
-
Setting properties such as number of decimal places, units of measure, currency and rounding
-
Displaying or hiding sign
-
Hiding or Displaying Leading Zeros
