Hi,

I am sure, you used same context binding for both dropdowns. I suggest you, if you are using BAPI for dropdowns, use different function modules for each. Use different name (Copy & Rename).

it will solve you problem

Example:

Artists (node)
-- Name (attribute)
Albums (node, supply function = supplyAlbums)
-- Title (attribute)

ArtistSelector (DDByIndex) "texts" -> Artists.Name
AlbumSelector (DDByIndex) "texts" -> Albums.Title

Assign an action "ArtistSelected" to the "onChange" event of ArtistSelector:

void onActionArtistSelected(...)
{
  wdContext.nodeAlbums().invalidate();
}

void supplyAlbums(...)
{
  IArtistsElement artist = wdContext.currentArtistsElement();
  /* create/add elements for this artist to node Albums: */
  ...
}

hi

The drop down index has a property by name "onSelect". You can bind an action there. Write the code to change the values in the second DDI. This is basically changing the values in nodes based on an other. Hope it helps.
