How refresh a Dynpro

[Former Member]

Hi,

I'm using 2 ALV Grid in a dynpro.

On the top I have a frame with some text fields that I use as header.

When I click on the ALV grid I can update the other one but I can't update the header or better ... the sceen does'n refresh.

I'm tryng using Call Screen and it works but I know that it's not the best solution...

How can I resfresh the dynpro...

Thanks

Salvatore

Hello Salvatore

Have a look at my sample report ZUS_SDN_TWO_ALV_GRIDS in thread [ALV|;.

In the event handler method for DOUBLE_CLICK I call the following method:

CALL METHOD cl_gui_cfw=>set_new_ok_code( 'DETAIL' ).  " not 4.6c compatibe, use instead

CALL METHOD cl_gui_cfw=>set_new_ok_code
   EXPORTING
     okcode = 'DETAIL'
*  IMPORTING
*    rc = 
    .

This method call triggers that the PAI of the screen is passed and, thereby, PBO of the same screen, too. In the PBO module(s) you can refresh your header.

Please note that normal ALV grid events do NOT trigger PAI of the screen (similar behaviour like F4 search help).

Hi Salvatore,

Update of Table

• Implementation in Component Controller for Update

IPublicTableTransactionComp.ITableNodeElement element;

Zstable table = new Zstable();

update.setPo_Type("M");

int size = 0;

int sizeMax = wdContext.nodeTableNode().size();

for(;size<sizeMax;size++)

{

element = wdContext.nodeTableNode().

getTableNodeElementAt(size);

table.setCust_No(element.getCustNo());

table.setFirst_Name(element.getFirstName());

table.setLast_Name(element.getLastName());

table.setPhone_No(element.getPhoneNo());

table.setOrg_Code(

wdContext.nodeZs_Dislay_Table_Input().

currentZs_Dislay_Table_InputElement().

getPo_Org_Code());

update.addLi_List_Of_Users(table);

}

try

{

wdContext.nodeZs_Update_Table_Input().

currentZs_Update_Table_InputElement().

modelObject().execute();

wdContext.nodeOutput_Update().invalidate();

if(!wdContext.nodeOutput_Update().

currentOutput_UpdateElement().

getPo_Success().equals("1"))

wdComponentAPI.getMessageManager().

reportWarning("UNSUCCESSFUL UPDATE");

else

wdComponentAPI.getMessageManager().

reportSuccess("SUCCESSFUL UPDATE");

}

catch(Exception ex)

{

wdComponentAPI.getMessageManager().

reportException(ex.toString(),false);

}

Implementation in View for Update

1. In the “Action” tab of StartView define an action “Update” and associate it with “OnAction” property of Button “Update”

2. In the eventhandler for the button in “Implementation” namely “OnActionUpdate” write the following code:

//Executing the Bapi on Click of Update Button

wdThis.wdGetBokApplCompController().executeZs_Update();

Declaration of Method executeChange

This method is defined to execute actions of updating the table with latest changes. We create method with “Type” as parameter in it.

9. Diagram describing Method executeChange and its Type being parameter

public void executeChange( java.lang.String Type )

{

//@@begin executeChange()

IPublicTableTransactionComp.ITableNodeElement element;

Zstable table = new Zstable();

update.setPo_Type(Type);

int size = 0;

int sizeMax = wdContext.nodeTableNode().size();

for(;size<sizeMax;size++)

{

element =

wdContext.nodeTableNode().

getTableNodeElementAt(size);

table.setCust_No(element.getCustNo());

table.setFirst_Name(element.getFirstName());

table.setLast_Name(element.getLastName());

table.setPhone_No(element.getPhoneNo());

table.setOrg_Code(element.getOrgCode());

update.addLi_List_Of_Users(table);

}

try

{

wdContext.nodeZs_Update_Table_Input().

currentZs_Update_Table_InputElement().

modelObject().execute();

wdContext.nodeOutput_Update().invalidate();

if(!wdContext.nodeOutput_Update().

currentOutput_UpdateElement().

getPo_Success().equals("1"))

wdComponentAPI.getMessageManager().

reportWarning("UNSUCCESSFUL ");

else

wdComponentAPI.getMessageManager().

reportSuccess("SUCCESSFUL ");

}

catch(Exception ex)

{

wdComponentAPI.getMessageManager().

reportException(ex.toString(),false);

}

//@@end

}
