Drop Down list in table with data from database table

Question

Hi,
I have created an interactive form in WD ABAP.
In Context tab I have created the nodes as follows:
ZSOHEADER node with cardinality 1..1
|-> MATERIAL node with cardinality 0..n. Under MATERIAL node there are 2 attrib. MAKTX and MATNR.
I am fetching data from MARA table into an internal table IT_MARA.
The node MATERIAL is bound to internal table IT_MARA.
I have created a table with property ' Body rows vary depending on data ' .
I have only one row in table. The first cell of the row is a drop down field.
I have bind the field to the node MATERIAL->DATA->MAKTX.
Now the issue is even though I have created only one row in my table, in preview it is creating as many rows in the table as the no.of records in the internal table.
I want only one row with the drop down list containing all values of the internal table.
Kindly suggest what to do.
Regards,
Vinod

Hi,
In the WebDynpro Context, in the main node create another node like A1 with cardinality 0..n and in this node create attributes TEXT and VALUE.
Now goto method and in that method using code wizard read the node A1.
And use the below code snippet sample in your program, i.e. code this under respective method of the webdynpro.
*Declare the TYPES
TYPES : BEGIN OF TY_TABLE,
TEXT TYPE SOMETYPE,
VALUE TYPE SOMETYPE,
END OF TY_UOM.
*Define Internal Table and work area.
DATA : IT_TABLE TYPE STANDARD TABLE OF TY_TABLE INITIAL SIZE 0,
WA_TABLE TYPE TY_TABLE.
SELECT TEXT VALUE FROM TABLENAME INTO TABLE IT_TABLE.
lr_node_info->bind_table( IT_TABLE ).
And in the Adobe Form Layout
Go to Menu of the Adobe LiveCycle Designer:
Tools>Options..>DataBinding
In that window you just check the Show Dynamic properties Check Box.
Now for the Drop Down go the binding tab in object palette and click on the list items and there specify the Internal Table and specify the text as the internal table text field and value as internal table value field.
OR
From the WebDynpro Native Library Palette use the Value Help Drop Down and in object pallette goto binding tab and provide the form interface binding. Before this in the WebDynpro goto Context and for the particular field under the properties provide the search help as dictionary search help and specify the name of the dictionary search help.
OR
We have another method of setting the Text and Value to the DDL directly in the WebDynpro by coding in the methods, I dont have much knowledge on this.
