Dropdown in Attribute

[Former Member]

Can any one help me out of doing dropdown for a attribute.

From database i'm selected the values and holding in a internal table(1 column).

How can i assign the internal table values into the attribue.

Thanks,

Hi Suba,

Use the following code to map your internal table entries (in the cdoe snippet below the itab is i_carrid) to the context attribute bound to the dropdown UI element.

NOTE: Context bound to the dropdown element (DROPDOWN in this example) must be an attribute of type string.

METHOD WDDOINIT.

DATA i_carrid TYPE TABLE OF sflight.

DATA wa_carrid TYPE sflight.

DATA wd_node_info TYPE REF TO if_wd_context_node_info.

DATA value_set TYPE wdr_context_attr_value_list.

DATA wa_value_set TYPE wdr_context_attr_value.

SELECT * FROM sflight INTO TABLE i_carrid.

LOOP AT i_carrid INTO wa_carrid.

MOVE sy-index TO wa_value_set-value.

MOVE wa_carrid-carrid TO wa_value_set-text.

APPEND wa_value_set TO value_set.

CLEAR wa_value_set.

ENDLOOP.

wd_node_info = wd_context->get_node_info( ).

wd_node_info->set_attribute_value_set( name = 'DROPDOWN' value_set = value_set ).

dbtag_key_item type wdy_key_value.

DATA lo_nd_ztraindat TYPE REF TO if_wd_context_node.

lo_nd_ztraindat = wd_context->get_child_node( name = wd_this->wdctx_ztraindat ).

dbtag_key_item-key = 'SUN'.
