Changing the Display of Numeric Values 

Use

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.

Features

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

·        Hide or display leading zeros

·        Determining Display of Empty Cells

The following is valid for all of these functions:

Determining Decimal Places, Units of Measure, Currency and Rounding

You determine the number of decimal places, along with the unit of measure, currency and rounding for each column individually.

Methods

Function	Class	Method
Determine number of decimal places	CL_SALV_COLUMN	SET_DECIMALS
Get number of decimal places		GET_DECIMALS
Determine unit of measure		SET_CURRENCY
Get unit of measure		GET_CURRENCY
Determine currency		SET_QUANTITY
Get currency		GET_QUANTITY
Determine rounding		SET_ROUND
Get rounding		GET_ROUND

For columns with DDIC reference, the GET_DDIC_DECIMALS of class CL_SALV_COLUMN returns the number of decimal places that is set for the referenced data element.

Displaying or Hiding sign

By default, positive numbers are displayed without sign, and negative numbers are displayed with sign. You are able to determine that the sign (-) not be displayed for negative numbers.

Methods

Displaying or hiding sign	CL_SALV_COLUMN	SET_SIGN
Checks whether sign is being displayed or hidden		HAS_SIGN

Hiding or Displaying Leading Zeros

For columns with data types n or NUMC (numeric text), the places that are in front of the value are filled with zeros (0). You are able to hide or display these zeros in front of a value.
