RAP action update item with same part of key

[former_member5334]

Hi experts

I created application for editing table and some actions using RAP.

I use behavior definition with managed scenario for editing fields my z-table(ZPO) with (vbeln, posnr) keys.
When i call an action for vbeln = '1000000001' posnr = '001' i need to update the all items with the same vbeln = '1000000001'

For action there is only 1 cardinality :

action myAction result [1] $self;

Can I call action for one line but update all lines with the same vbeln ?
