Creation of web Dynpro component
Transaction used : SE80
Create a view for ALV and check whether alv is getting displayed or not. If the alv is not displayed kindly check and correct it to get the alv displayed.
Now decide the column in which you want to display the drop down as per the requirement given to you.
In the example here I have taken the column name as ‘TYPES’
Now add an attribute say VALUESET in the node of the ALV
