Summary

Trying to show Master and child relational data from Table A and Table B

Content

Hi, I've two Business Objects A and B. (B has A.id as a reference object)

B is many to one to A.

I've built tables on A and B. And I need to Show the contents of B when I select a row from table A. Also, I need to have a create functionality where when I Create a row in A, I can also add contents to B on a single page. Is there a way to do this? I tried with idAttribute but it gives an error.
