Db link tables in processes and row fetch

Question

I have an application I developed in schema A that is referencing tables in schema B. I have been told that these tables need to be moved to another database for which I have created a database link. I know this database link is working because it tests ok and I can pull user names from a user table in an item.
Also, on the first page I have a report that sources from the dblink:
SELECT TRK_CALLS.ID, TRK_CALLS.USER_, TRK_CALLS.ASSIGNED_TO, TRK_CALLS.PROBLEM, TRK_CALLS.SOLUTION, TRK_CALLS.STATUS
FROM TRK_CALLS@DBLINK_IM3
WHERE
( STATUS = 'Open' and :P2_REPORT_SEARCH is null )
or
( regexp_like( USER_ || '#' || ASSIGNED_TO || '#' || PROBLEM || '#' ||
SOLUTION || '#' || STATUS, :P2_REPORT_SEARCH, 'i' ) )
This is working correctly.
I have edit buttons for the rows in the report that redirect to page 6. I get any error unable to fetch row.
In the row source I placed
trk_calls@DBLINK_IM3
I only have one selection as table owner WEBB so this may be part of the problem but I am not sure how to fix this. I tried to create a new row fetch under the the owner GIS which is the right owner but it still diplays WEBB once created. Is this even part of the Solution?
Is there a better way to do this? PL/SQL expression?
I have many other processes that will have insert, apply changes, etc to the tables so if I can get this to work I may be on my way to making the db link work.
Please help me in any way possible.
Thanks,
Kirk

Kirk,
you get this error because it is impossible to use the returning clause, probably because you are using a DB link.
You can cicrumvent this by determing the primary key value in the PL/SQL before doing the insert and then including its value in the insert:
Thanks alot for the info on creating the view. It is working to a certain point.
I am getting a 'ORA-22816: unsupported feature with RETURNING clause' error now. I created the view and referenced the view in all of my pages. Simply put, wherever I had TRK_CALLS in a source or SQL expression I replaced it with TRK_CALLS_VIEW.
The application didn't have the error before and the only thing I changed was this. What could be the problem?
This is the expression that the error is referring to:
declare
l_CALL_ID number;
begin
/* determine CALL ID */
i_call_id := get_call_id; /* some function returning new call id */
insert into webb.TRK_CALLS_VIEW
(+id+, USER_, ASSIGNED_TO, PROBLEM, SOLUTION, STATUS)
values
(+i_call_id+,:P3_USER_, :P3_ASSIGNED_TO, :P3_PROBLEM, :P3_SOLUTION, :P3_STATUS)
good luck, DickDral
