Features of Lists

The main purpose of a list is to display data with a minimum of programming efforts.

Lists also take the special requirements of business data into account:

• Lists can de designed as multi-language units: Texts and headings appear in the log on language, provided an appropriate translation is available.
• Lists can display monetary values in the appropriate currency.
  

The following options are available when programming a list:

• Screen: You can add colors and icons
• Printers
• Internet and Intranet: Automatic conversion to HTML takes place for this.
• Save: This is possible both within tha SAP System as well as outside of it (for further processing-for example, through table calculation programs).

• You create lists using the WRITE statement.
• You can create simple lists and complex lists with events.
• Using the ULINE statement, you draw a horizontal line in the screen.

To format the output of a list you can use the following ABAP STATEMENTS:

• COLOR<color> : Adds color to the background of the text
• LEFT JUSTIFIED: Aligns your text to the left
• RIGHT JUSTIFIED: Aligns your text to the right.
• CENTER: Aligns your text to the center
