dynamic alv dropdown values

$

Hello,

 

I have the ff requirement:

 

1. Create an Editable ALV.

2. User can enter data by clicking append row or insert row.

     - Take note that the table has no data yet, user will input the data.

3. Most of the columns should have dropdown values.

     - I don't have problems with columns that have same data per row - I used dropdownbykey.

4. Here's the catch, some of the columns are dependent on the data entered in other columns.

     Example: I entered country in one field, I should ONLY be seeing the users under that country in the adjacent field.

     - By this time my context node is still initial because i'm still editing the row.

     How can I achieve this?

     I can't use dropdownbyindex because, as per the posts that I've read, the alv is already populated.
     In my case, I'm yet to populate the ALV.

 

Thanks.
