Caps - capital letters.

Sir what do u mean by post not in caps.
All caps is generally considered shouting in the internet, don't do it.
Are the users trying to modify the same set of records?

You do realise that everyone on this forum has a day job that's just as urgent as what you are doing?
You need to be patient - if you want immediate answers hire a consultant.
Are you sure the problem is on insert?
Because your last post indicates that sub block is pre-populated with data which the user updates by checking the checkbox.
Basically though this is due to some code you've written in the form. Forms default processing does not behave this way.
So you've got some code in some trigger that is locking a record and when another user runs the form that code tries to lock the same record the first user has.
You need to work out which trigger is being fired when the form hangs. Either run the form in debug mode or add messages to each trigger so you can see which one is being run when.
Once you've worked out which trigger is causing the lockup it should be fairly simple to work out what the problem really is.

which is linked with detail block through primary foreign relations

Unfortunately I get an encoding error when I open your form so I can't read any of the triggers.
So can you give the following:
1) The full code of the WHEN-BUTTON-PRESSED trigger on design_ok
2) The full code of the WHEN-CHECKBOX-CHANGED on chk_design
3) Details of how the SALE_COMBINATION_SUB_DETAIL block is populated - I'm assuming you just use default query functionality.
4) Details of any insert/update/delete statements against the SALE_COMBINATION_SUB_DETAIL table in the form.

1. What are the primary keys of SALE_COMBINATION_DETAIL and SALE_COMBINATION_SUB_DETAIL?
Where are the procedures FILL_DETAIL and FILL_DESIGN_DETAIL called from?
sale_combination_sub_detail.sale_comb_no = sale_combination_detail.sale_comb_no and
sale_combination_sub_detail.sale_comb_date = sale_combination_detail.sale_comb_date and
sale_combination_sub_detail.product_code = sale_combination_detail.product_code and
sale_combination_sub_detail.party_id = sale_combination_detail.party_id
2. Where are the procedures FILL_DETAIL and FILL_DESIGN_DETAIL called from?
canvas display
block control
push button(enter)

I asked for the primary keys of the tables not the relationship between them.

run the following sql and post the results:
SELECT uc.table_name, uc.constraint_type, uc.constraint_name, ucc.column_name
FROM user_constraints uc, user_cons_columns ucc
WHERE uc.constraint_name = ucc.constraint_name
AND uc.constraint_type IN ('P', 'U')
AND uc.table_name IN ('SALE_COMBINATION_DETAIL', 'SALE_COMBINATION_SUB_DETAIL')
ORDER BY 1,2,3;

Why didn't you just say so?
Can we confirm if it the post command is causing the hang or something else in that trigger?
If you haven't already put messages in that trigger before and after the post command, one inside the loop, one before the hide view command and one at the very end.
Let me know which message is the last one you get before it hangs.
Also you said this:
Quote:
one user open the form data fetch auto primary key data (1,sysdate)
Which tables primary key and which columns?
Are there any database triggers on either of the tables:
select trigger_name, trigger_type, triggering_event, table_name from user_triggers where table_name in ('SALE_COMBINATION_DETAIL', 'SALE_COMBINATION_SUB_DETAIL')
I'm really confused by your design. Why does SALE_COMBINATION_SUB_DETAIL not have primary key?
Why are you populating blocks using cursors?

three tables used in this form
1. sale_combination_master
one user open the form data fetch auto primary key data primary key (sale_comb_no,sale_comb_date)(1,sysdate)
2. sale combination detail
primary key (sale_comb_no,sale_comb_date,product_code,party_id)
(1,sysdate,'0001','buff-00901')
foreign key (sale_comb_no,sale_comb_date) relation with sale
(1,sysdate)
combination master table
3. sale combination sub detail
foreign key (sale_comb_no,sale_comb_date,product_code,party_id)
relation with sale combination detail table
(1,sysdate,'0001','buff-00901')
first time when first user open new block (sale combination sub detail) & tick some data as per requirement press ok to return back to main screen then no problem
after that choose next record in sale combination detail & press button to again open sale combination sub detail block then tick some data as per requirement & press ok then on post keyword system hang
if in between second user close the form then for first user
system can work & cursor move from post keyword
no database trigger used
