I have created Master Detail form of Sales offer. I would like to enter item detail under Sales offer detail.

Example :

Sales Offer Header -> Sales Offer Detail -> Sales Offer Detail Detail.

I have tried to make a form in form 6i to fulfill above mention scenario. But when two or multiple users tried to enter data from this form all users entered into deadlock or hang stage. Kindly provide solution for above mention requirement.

We would need to know which records are getting locked.

It shouldn't be.
Oracle only locks the specific records you are trying to change. It locks them as soon as you start modifying them and releases the lock when you commit. That's the default behaviour.

Are the users querying the same set of records in the 2nd block?

Oracle only locks the specific records you are trying to update/delete but when some one inserting any record in that table oracle locks the complete table till commit/rollback.

Again that shouldn't happen.
Is it just the 3rd block that does that or all three?
Do you have any pre/post-insert forms triggers on the problem block?
Do you have any insert database triggers on the table the problem block is based on.

Ok so what does the pre-insert trigger actually do?

Exact code please - I really can't diagnose an issue with incomplete information.

You've got some code somewhere that's doing the locking, oracle's only doing this because you told it to, and the pre-insert trigger is the most likely culprit at this point.

Sorry that I have been so long in replying. Have you solved your problem?

Perhaps you should move that code to a database trigger.
