DropDown by Key in WD_SALV

[former_member509430]

Hey there,

I have an Application with an WD_SALV Grid. The Grid contains two Fields, which have a CELL_EDITO set to DROPDOWN_BY_KEY.

At WDDOINIT the first field is filled with main-categories. That's all fine. In order of the choosen value, the second field should have the right valueset for the secondary categorietypes for the main category.

I catch the Event "CHANGE" of the DD_BY_KEY and read the choosen Category. Then I select the secondary categories for the choosen one and bring it over the NODE_INFO-Reference with SET_ATTRIBUTE_VALUE_SET to the Node at the right field. All is fine an no Error comes up. But in the ALV the DD-Field is empty.

What is my mistake? Can anyone help me??

Best regards

why dont you write some code in ONSELECT action of first ddbk .

write code conditionally.....if first ddbk value is xxxx then one value set for second ddbk or if it is yyyy then another valuesset.

First, I tried to do this. But nothing happend. It's the Event "CHANGE" of the ALV-Grid (SALV_WD_TABLE). I wrote my Code to a separate Method and called this Message from various other Methods. From WDDOMODIFY, from the Eventhandler for the CHANGE-Event and at WDAFTERACTION.

The effect I want to get, I did'nt get.

I think, that you can only put new valuesets at WDDOINIT to a node. Is that right?

You can write valuesets in any method..

OK. Thanks for your quick answer!

Here is my code:

DATA: lr_nd_detail TYPE REF TO if_wd_context_node,

lr_nd_info TYPE REF TO if_wd_context_node_info.

DATA: lt_dd_value TYPE wdr_context_attr_value_list,

lt_kat TYPE /otto/mss_t_kat1tx,

lt_kat2 TYPE /otto/mss_t_kat2tx.

DATA: ls_dd_value TYPE wdr_context_attr_value,

ls_kat TYPE /otto/mss_kat1tx,

ls_kat2 TYPE /otto/mss_kat2tx.

• Knoteninfo-Referenz

lr_nd_detail = wd_context->get_child_node( 'DETAIL' ).

lr_nd_info = lr_nd_detail->get_node_info( ).

• Daten für Hauptkategorien lesen

SELECT * FROM /otto/mss_kat1tx INTO TABLE lt_kat

WHERE langu = sy-langu.

MOVE lt_kat TO wd_this->t_kat1.

LOOP AT lt_kat INTO ls_kat.

MOVE: ls_kat-id TO ls_dd_value-value,

ls_kat-text TO ls_dd_value-text.

APPEND ls_dd_value TO lt_dd_value.

ENDLOOP.

• Werte in die Knoteninfo eintragen

lr_nd_info->set_attribute_value_set(

EXPORTING

name = 'KATEGORIE'

value_set = lt_dd_value ).

This I do at WDDOINIT. All is fine and the DropDown is filled!

At ON_CELL_ACTION of the ALV-Grid, I did the same for the second DD-Field, but the field is already empty. So where is my mistake?

Hi..

lr_nd_info->set_attribute_value_set(

EXPORTING

name = 'KATEGORIE'

value_set = lt_dd_value ).

In above statement KATEGORE is second dropdown attribute name?

No. This is the code, which works. It's in WDDOINIT.

At ONCELLACTION I called a Method which has the same Code with EXPORTING name = 'KATEGORIE2', which is the Field of the second DD-Field.

[former_member199125]

It means ONCELL Action method is not triggering. You can test it by putting break point in onaction cell method.

Please check why its not triggering

ONCELLACTION is triggered. My breakpoint is in the Method and I can see in the Debugger, that the selected Values are transported to the node attribute. But I can't see them in the Grid.

[former_member199125]

Its strange behavior.

Ur method is triggering... valueset binded to attribute.. Did you bind the same attribute at to table column?

Thanks for your link. It doesn't match my problem.

You see, I filled my DropDownbox, so I know how to set it up. But the second fields values should be in order of what you select at the first. But my DD-Field is empty after setting the valueset to the node.

Any other tips??
