Define and Describe ALV

  • The ALV (ABAP List Viewer) is a flexible tool for displaying lists in SAP.
  • The tool provides common list operations as generic functions and can be enhanced by user-defined options.
  • This allows you to use the ALV grid control in a wide range of application programs.
  • For this module, the simplest way to use ALV will be discussed. Advanced topics in ALV may be discussed in the later part of the Training.

The ALV Field Catalog


  • The field catalog is an internal table which contains information about the fields to be displayed on the ALV. The type is SLIS_T_FIELDCAT_ALV.
  • We must first build the field catalog before displaying any output in the ALV.
  • There are many fields in the field catalog but for a simple output, the only necessary fields are FIELDNAME and SELTEXT_L.
