Apply Filters to SALV Table

In the series of the SALV Model Table display in SAP ABAP, today we will see how to apply Filters to the ALV Grid. You can find all the Previous discussion at Tutorials > SALV Table Display .

Filters are important to display only values required by the users. i.e. See only the “Red” Lights from the Traffic Light report. To achieve this functionality, we have the CL_SALV_FILTERS class of SAP OM.

We can use the method ADD_FILTERS of the class CL_SALV_FILTERS to apply the filter on a specific column. The values in the filters would work exactly like values in a Range or Select-options i.e. SIGN, OPTION, LOW & HIGH. For this example, I have applied filters on the ERDAT column to only show records with a specific date.
