How To Hide Overview Assignment Block Dynamically

It is possible to detach or reattach assignment blocks in a BSP overview page. First thing to do is determine the name of the assignment block that we want to hide. There are two possibilities for this purpose

  • If the block we want to hide is a defined as a component usage in our BSP, the name of the assignment block should consist of the usage name and the interface name seperated by a dot

'component_usage_name'.'interface_view_name'.

  • If the block is defined in our BSP component,  the name should consist of the component name and the view name seperated by a slash symbol

'component_name'/'view_name'

 

In order to hide the assignment block of which name we have just determined, we need to redifine the method DETACH_STATIC_OVW_VIEWS of the controller class of the overview page using the redifine button

 

Next we insert the code to do the hiding under the conditions we provide

DATA: ls_viewid TYPE bsp_dlc_ovw_stat_view_attach.
  	CONSTANTS: c_view_id TYPE string VALUE 'ZCoUsGSCM.MainWindow'.

  	*IF control
    	ls_viewid-viewid = c_view_id.
    	APPEND ls_viewid TO rt_viewid.
  	*ENDIF.

 

Similarly, we need to redefine the REATTACH_STATIC_OVW_VIEWS method to reattach the hidden assignment blocks

 

And insert the following code

DATA: ls_viewid TYPE bsp_dlc_ovw_stat_view_attach.
  CONSTANTS: c_view_id TYPE string VALUE 'ZCoUsGSCM.MainWindow'.

*  IF control.
    READ TABLE view_area WITH KEY appl_viewname    = c_view_id
                                          type     = space
                                          traymode = abap_undefined
                                          TRANSPORTING NO FIELDS.
    IF sy-subrc = 0.
      ls_viewid-viewid = c_view_id.
      APPEND ls_viewid TO rt_return.
    ENDIF.
*  ENDIF.
