Creat a button and put that code in when_button_pressed

declare
v_a number;
v_b varchar2(300);
cursor xyz is select (M_ID, NAME, RAM, HDD, PROCESS, LPO_ID, WARRANTY, D_TYPE)
from Models
where MODELS.LPO_ID = :BLK_LPO.LPO_ID
order by m_id;
begin
open xyz;
loop
fetch xyz into v_a,v_b;
exit when xyz%notfound;
:TEST1.TSTUID:= v_a;
:TEST1.TN := v_b;
NEXT_RECORD;
end loop;
close xyz;
end;

replace some code with your exact fields.

I wouldn't do it that way. @alhanashi's situation is a classic example of master-detail relationship. Therefore, all that should be done is to follow Data Block Wizard's instructions and let it do the job. If foreign key constraint exists between these two tables, Forms will know how to create a join condition. Otherwise, create it manually.

Doing that, querying master (LPO) block will automatically retrieve detail records (MODELS); you don't have to write a single line of code.

Why would you do that? Forms runtime already contains a toolbar which fits most of your needs (at least, "save" and "query"; what do you mean by "update", anyway?).

Create three Button
1. Save
Issue this command:

declare
begin
commit_form;
next_record;
end;

2. Search(Enter Query) (When Button Pressed)

Deaclare
Begin
Enter_query;
end;

3. Update Button

Too much typing for nothing. If you insist, what's wrong with just

commit;

enter_query;

in the first two triggers?

Also, I'm curious what would that "update" button do.
