How to Add logic to change quantity of child item(Template BOM).

Question

Now We use ver 2004B.
2004B has bug about Sales Bom,The Bom can't be expanded correctly using UI-API.
We have to using BOM Both UI-API and GUI,so we use Template Bom(in UI-API we expand the BOM by ourselves).
Now we face two problems.
1. In Template BOM,when change parents item's quantity,
child item's quantity don't change.We must make UI-API logic to change child item's quantity,but we don't know which event should we catch.
2. We have to add another logic,when expanded Template
BOM (using GUI),setting zero price specific item.But don't know which event should we catch.
Focus lost event may not use,because focus lost event triggers too much timing(for example,displaing a list of item,expanding BOM etc...).
Please suggest us how to do.
thank you.

Hi Ibai Peña
I tried logic which trrigerd Validate Event,but I face a
new probrem.
・When trrigerd Validate Event ,and add something value to other field, trriger Other Validate Event.
To avoid this problem, I use a variable which type is bool using flug triggerd process.
But I think this way is not so sensible, I want to take other way.
thank you.
