Hi,

Probably both DDB Key and DDB Index may not be suitable for implementing your requirement. Sometimes reusing existing ABAP dictionary search helps is not sufficient for example: when the value help should take into account or fill multiple input fields of your view composition.

Your requirment may need some programming to be done and you may need to use a different type of value help referred to as the Object Value Selector (OVS).

Thanks,

i think arpan has already outlined. I would model it like a master - detail, every master has 0..n detail records.

In that sense if you bind two of your DDBI to two different nodes and fill the first node and on every selection of master retrieve the details. You can very well use the supply methods to get the details records based on the master record.

Hi Rakshar,

1. Add an onSelect event to the Dropdown 1.

2. In the event handler get the the selected value of Dropdown 1 from the context of the same. Based on the selected value, retrieve the data to be displayed in Dropdown 2 ( for example data from a table)

3. Invalidate the context for Dropdown 2

4. Bind the data retrieved from table to the context for Dropdown 2 by using method BIND_TABLE

Let me know if you face any difficulty.

Regards,

Arpan
