begin trans and roll back - doubts

Hello

I have a doubt about begin and commit and rollback.

I have a proc x and in this proc I started a begin trans, inside of my proc x, it calls a proc xy.

In the proc x I have two deletes for two tables (product, sallers) and inside of my proc xy I have one delete for my clie table.


if I call the rollback, the rollback will affect all the tables from proc x and proc xy?

thanks
Alex
