FRM-40657: Record changed or deleted by another user.

Question

I have a forms module with a module component based on a view.
This view is a simple view with 1 base table.
This view has a 'client derived' primary key with a sequence.
This view has a instead of trigger, which is calling the table API.
There are no server derived columns etc.
When I insert a record via the form and try to update the same record
without requery, I get the message:
FRM-40657: Record changed or deleted by another user.
When I drop the trigger the error is not raised.
Any idea ?
Configuration:
Forms 6.0.5
Designer 6.0.5
Headstart 5.1
Oracle 8.1.7.4.0

Answer 1

From Documment : 1236623.1
Cause:
1. Navigation from (Responsibility) System Administrator > Security > User > Define > Query out the responsibility, found responsibility key is <NEW_VALUE>. ..................... This is wrong Navigation
2. Found value <OLD_VALUE> is included in column role_name of the responsibility under the user by sql statement:......................................................................................... Not sure whats the old Value
select * from wf_local_user_roles
where user_name = '<user_name>'
and role_name like '%<OLD_VALUE>%';
Solution :
4. Identify the Role (responsiblity) to be changed, click 'Show' to expand the record, select a date to field 'Active To' to provide an end date to this role assignment. ..... Not sure how to get role for particular responsibility.
From Document : 1273157.1
We have created new responsibility , But now we are getting error while END_DATE old responsibility.
New Responsiblity name : BPC-160 DC Staff-New
Old : BPC-160 DC Staff
