Doubt about how to read Entity data and change this data on NWBC screen with event.

[ronaldo_aparecido]

Hi guys,

I'm beginner in MDG and i have this problem:

I use NWBC in MDG step by step untill aprov.

I have a uibb with all plants linked with an entity .

I want to add and z button in UIBB and when i press it i want to call a badi like cross et

and copy data of first plant to other plants updating the others related uibb s too.

The badi is not trigered when i click in my button (are there a reason?)

the badi is called only when i change a field of screen and i only can read one entity.

I searched documents like this :

https://www.sap.com/documents/2015/07/666e4158-5b7c-0010-82c7-eda71af511fa.html

but i can not read many entities.

Is this a configuration problem?

Or are there a way to do it by code ?

if yes, please could send me a documentation?

thanks
