1) Create a child node  under main node of for which your table has been binded.

2) Child node  Cardinality should be 0..n and selecction should be 0..1

3) code for the values which needs to be displayed in Dropdown. and bind them to child node

4)  change the property of table column to dropdown by key

5) bind the child node values.

For ref : Example to use drop down by key and drop down by index In WDA

Hi Akansha,

Are you using DropDownByKey or DropDownByIndex ui element for drop down list box.

Please refer the below links

Drop down by index in Table in WDA…

SAP Web Dynpro ABAP - DropDownByKey value set setting

Hope this helps you.

Hi Akansha,

After creation of table in layout, Swap the element definition to which field u want drop down in the table. then automatically it'll appear in the output.

Right click on table cell and select  "Swap element definiton".  Then select Dropdown by Key.

hope it'll help.

Cardinality should be 0..n and selection should be 0..1 .
