SALV Limitations: Separator in Toolbar
In this new series on SALV Object Model (SALV OM), I will document some of the Limitations which are not documented in standard SAP documentation.
In the ALV GRID (created using container) type of SALV, we can't have a Separator in the Toolbar. To add the separator in the Toolbar, button type (BUTN_TYPE) field of toolbar must be set to "3". SALV OM doesn't allow to specify this button type. It assumes that there would be only normal buttons (BUTN_TYPE = '0'). Method IF_SALV_TOOLBAR_ADAPTER~BUILD_UIFUNCTION in class CL_SALV_GRID_ADAPTER, creates the toolbar functions.
Code Lines which impose this restriction in SALV OMTo overcome this limitation, SAP could enhance SALV OM to provide us the method to set the button type in the CL_SALV_FUNCTION and use that button type here in the code instead of assuming that button as the normal button.
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.
