Answer 1

my question
1- there is any way to assign the Fetch process to specific region so the process take all item in these region only.
2- how can create manual process to fetch row into specific items in page ( i tray these code
SELECT col1, col2, col3 ....
INTO :P1_ITEM1, :P1_ITEM, :P1_ITEM...
FROM table
WHERE id = :P_id ) but no data retrieve .
I do not think that it is possible to have more than one Automated Row Fetch process in a given page. See the thread:
ORA-01403: no data found : Unable to fetch row multiple automated row fetch
On your second question, the manual process should work provided:
P_ID has a value when the process executes. You can do it this way:
i. Make this process as a on-load After/Before header process
ii. Make sure that P_ID page item has value when the process executes (set it from another page or before the pl/sql process executes)
