Dropdown by index in ALV using in Web Dynpro

Summary:



Web dynpro
application to demonstrate how to implement drop down by index using ALV.

Some times
we may have a requirement to show the different values in each row of an ALV
using Drop down. This is possible with dropdown by index using which we can
assign different values to each and every row of an ALV. But it is quite
different to implement in ALV. Where as in Table ui element we usually create
one sub node under the parent node to fill the drop down values. In ALV we can
not do the same instead we will take one additional attribute to which we will
assign the value set.

Create a
Web Dynpro component named as Z_ALV_DROPDOWN_INDEX and also create component
usage for ALV.



Create a
context node as shown in the figure. Create one additional attribute VALUESET

with type WDR_CONTEXT_ATTR_VALUE_SET
to hold the values for drop down along
with required attributes.



Go to the
Layout and insert View container element and named it as VCU_ALV.



Now go to
the WDDOINT method to implement required logic.











Now go to
window right click on view MAIN to embed the Interface controller view.





Now create
an application to test the component and the output is.
