Hi
Solution 1. In your Main BO define association targeting to Preventive BO.
ex
association ToPreventive to Preventive;
then in absl set this association. In UI use this association to bind your data
Note: Association support 0..1 or 1..1 multiplicity, since you want to add as a list which will not support here.
Solution 2: in Data Model bind your data list (this may be under root of main BO) with Previnting BO.
- in Controler tab Create a new Query and for this query seletc BO model "Preventive BO"
- Bind Query with QueryByElements
- In General tab select AdvanceListPane for your tab and in property Defaultset Mapping select Defualt set.
You can configure your default set and pass parameter to filter the results.
Data of other BO will be shown in existing UI(created for other BO)
Regards
Sunil
