The user can also choose from the list of existing variants using the function module ‘REUSE_ALV_VARIANT_F4’. I_save = variant save condition ( A=all, U = user-specific )Ĭs_variant = internal table containing the program name (and the default variant-optional ) Sample code:ĬALL FUNCTION 'REUSE_ALV_VARIANT_DEFAULT_GET' The default variant can be found using the function module 'REUSE_ALV_VARIANT_DEFAULT_GET'. The user can programmatically set the initial (default) variant for list display. The variants in the list display can be both user-specific and general.

Internal tables to used in the program declared based on the above table types Sap standard tables types taken from the type pools are: The different steps used for getting the above function modules into use are : DATA DECLARATION The commonly used ALV functions used for this purpose are The report output can contain upto 90 columns in the display with the wide array of display options. This is a very efficient tool for dynamically sorting and arranging the columns from a report output. In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. Cases arise in SAP (Systems, Applications, Products in Data Processing) when the output of a report contains columns extending more than 255 characters in length.
This set of ALV functions is used to enhance the readability and functionality of any report output.
SAP provides a set of ALV (ABAP LIST VIEWER) function modules, which can be put into use to embellish the output of a report.
