Mru error

I'm getting the following error while trying to update rows in a table.
Error in mru internal routine: ORA-20001: no data found in tabular form
I checked against the sample application (page 8), I dont see anything wrong that I'm doing.
could you please help me figure out what the problem is?

I created the report in the following manner:
1. Clicked on regions
2. Selected reports
3. Then selected easy reports
4. Selected the table and the columns to be displayed
5. 3 of these columns are editable text boxes
6. Then I defined the cancel and submit buttons
7. then I defined the MRU process that would kick in on clicking the submit button.
the intention is to update the values in a table when the submit is pressed.

MRU Error : Current version of data in database has changed since user init

When i use HTMLDB Wizard to create Master Detail Form
(You can see step by step what i doing by see this url :
http://jroller.com/resources/w/wildan83/MRU%20Error.pdf
The is error in MRU :
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "A884FA378C851786DDFE3A33709CB23C", item checksum = "0EEFFABE8252B0B279DB14A77F567F5D"., update "CNAP2"."ENROLLMENT" set "STUDENT_ID" = :b1, "SECTION_ID" = :b2, "ENROLL_DATE" = :b3, "FINAL_GRADE" = :b4.
If there something missing.., just say ..
Thanks for the help.

Oh i see ..,i never think if that is the source of the MRU
error.
Ok ..,
Now ..., i have new question .., how can i change so the the primay key in detail table (enrollment table), i have one primary key with two columns .., if you don't understand what i mean ..,
check this alter table statement :
ALTER TABLE ENROLLMENT
ADD CONSTRAINT ENR_PK PRIMARY KEY
(STUDENT_ID
,SECTION_ID) ;
Now the question is .., when i using wizard to create master detail form .., html db automatically make student_id and section_id as the primary at "application level (html db)" .., how can i change this behaviour ..,
i want the html db not treat this two column as primary key ?
Do i have to create master detail form manually to accomplish this ?
Thanks before .., sorry if my english is not too good.

Computing default value for column MRU. error.

hi
we moved from apex 3.x to 4.2
AN apex application was working fine..After upgrade it gave error while trying to insert using apex front end
Error computing default value for column Apply MRU.
ORA-06550: line 3, column 46: PL/SQL: ORA-00972: identifier is too long
The PK of the relevant table is based in a sequence.Can i relplace old seq. using new seq...will it help?
When we insert using regular insert statement in sql developer, its fine though.
thanks

Hi,
Remember the error says "default value". What is your code to set the default value?
I've seen this error before where it was simply a statement like
column = "text123456789012345678901234567890";where the identifier error was given because it should have been
column = 'text123456789012345678901234567890';Since the string doesn't begin with an apostrophe, the parse thinks it's a LONG identifier. Hence, error!

MRU Error in Tabular Form

Hi
I created a tabular form. Also created a trigger that would insert a sequence number, user and system date each time a new record is inserted. I have associated an existing LOV to one of the fields.
I hit the 'Add Row' button. Select a value from the LOV for the account code. Hit the submit button and page indicates 1 row inserted.
I hit the 'Add Row' button again to insert another row and the following message appears:
Error in mru internal routine: ORA-20001: Error in MRU: row= 0, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "F246ADAF68494BEE51356ECC92B1047C", item checksum = "B9E444CAB12B67D92A5DBC8BB3E48517"., update "TEST"."VIEW_ACCOUNTS" set "CONTROL_SEQUENCE" = :b1, "ACCOUNT_CODE" = :b2
If I come completely out of the application and go back in to insert another record, I get the same error.

Hi,
I think above probem is caused by the trigger created.
Check without the trigger for test-purposes and check if the error is gone. ( checksum error, I suppose )
Kind regards,
Iloon

Tabular Form Unable to update : MRU error

Hi,
In debug mode, I got that message when I try to update the only row I have in that form :

0.08: ...Process "ApplyMRU": MULTI_ROW_UPDATE (AFTER_SUBMIT) #OWNER#:PROMOTION_ASSIGNEE_PROD_TMP:PROMO_ASSIGN_PROD_SEQ:pro_no_promotion_assignee

0.09: Performing rollback...
Error in mru internal routine: ORA-20001: no data found in tabular form
What can I do ?
Thank you.

The tabular form wizard creates a display report column for your primary key column in addition to the actual hidden column that stores the PK for MRU processing. To differentiate the display column from the hidden column, it gets a different alias by appending a suffix to the primary key column's name. That suffix plus the PK column name can't exceed 30 characters, and the suffix is 8 characters long, so this leaves 22 characters for the PK column name. Clearly this implementation has some room for improvement, and I expect that we'll address this in a future version of APEX.

Why "Error in mru internal routine..." ?

Hello !
I have two tables SITES( site_pk, site_name,...) and SITE_DOKU( doku_pk, fk_site_pk, doku_det1, doku_det2, doku_date,...).
The primary keys are set by before insert triggers which retrieve NEXTVAL from a sequence.
Not for every SITE there is a SITE_DOKU record, but if one exists, no other for this site can be created.
I created a view SITE_VIEW as an outer join of the above tables:
CREATE OR REPLAVE VIEW SITE_VIEW AS
SELECT S.site_pk, S.site_name,
       D.doku_pk, D.doku_det1, D.doku_det2,...
FROM SITES LEFT OUTER JOIN SITE_DOKU
         ON D.site_pk = D.fk_site_pk
/For insert, update and delete I created INSTEAD OF triggers which call procedures from a package.
In my APEX-application I created a tabular form based on this view.
The wizard asked for a primary key and I descided to take doku_pk.
I thought it's not really of interest, because handling of insert and update is managed by my instead of triggers.
To be on secure side in the instead of update trigger I tried an update and if it would fail ( %ROWCOUNT attribute = 0 ) I did an insert.
Two scenarios for my application:
A) There are two records displayed in my form:
SITE_PK SITE_NAME DOKU_PK DOKU_DET1 DOKU_DET2
101      Sitename1
102      Sitename2 1001     valuedet1This means: for site 101 there doesn't exist a site_doku record, for site 102 there is site_doku record 1001
And now the behaviour of the tabular form: if I fill in a value in item DOKU_DET1 for the first line (it is therefore an insert into SITE_DOKU) or try to update the second line I get a checksum error:
"Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum =..."
B) There are two records displayed in my form:
SITE_PK SITE_NAME DOKU_PK DOKU_DET1 DOKU_DET2
201      Sitename1 2001     valuedet1
202      Sitename2This means: for site 202 there doesn't exist a site_doku record, for site 201 there is site_doku record 2001
And now the behaviour of the tabular form: if I fill in a value in item DOKU_DET1 for the second line (it is therefore an insert into SITE_DOKU) or try to update the first line everything works well: there is an update or insert into SITE_DOKU !
Can anyone please exactly describe how APEX is handling the two not so different situations, in the first case resulting in an error, and in the second case working as I expect ?
BTW: I found a workaround (or solution) in changing the primary key definition for the view to SITE_PK. Everything is working now, but I want to understand how APEX is working !

Heinz

Heinz,
There are a number of things happening when rendering and saving tabular forms. While rendering the form, the data is read from the database and shown in your tabular form. There are also checksum values built for each row by concatenating the values of your editable columns and building a checksum on the resulting string.
Then, after you entered your data and clicked the apply changes button, for each row the engine checks if there has been a change, and if so, the engine retrieves the current data for each row from the database, builds a checksum on that data and compares the checksum value with the checksum value that was computed when rendering the form. If the checksums match, the engine performs the update otherwise it raises an MRU error.
All of this is done based on your PK. And if the PK is NULL, then the engine assumes this is a new row and attempts an insert. In your case, I think your first scenario fails because the column you chose as PK is NULL, so the engine can't identify the correct row in the database. With your work-around / solution, using a different column as PK, you basically ensure that each records can be properly identified.
Hope this helps,
Regards,
Marc

Error in tabular form

On a wizard generated tabular form on a table, I keep getting
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process.
when I click the Apply Changes button.
The data has definitely not changed.
How do I go about troubleshooting this? I did add some derived fields to the SQL query that the wizard generated, but they are not Editable, they are read-only fields.
I am at my wits end.
Thanks

Marc:
I did the latter thing. I started with the wizard generated form, made sure it was working and added my changes one at a time, keeping my fingers crossed after each change! Its still fine.
<rant>
See the frustrating thing about the MRU error is that it gives absolutely no indication as to what the real problem is, it doesnt help to fix it. So basically one has to "backtrack" all the way to the beginning, the same way I did above i.e. start all over again. Its very time-consuming and counter-productive.
</rant>
Marc: Is there a way you can basically prevent changes to the wizard-generated form that would make it "not work" anymore?
Thanks

Multi Row Update Error

Hello Everyone
I get the following error when attempting to perform a multi row update. Is anyone able to advise what the issue is?
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "F71A42E70B86E7C8A14343633169264E", item checksum = "43A7146FE322237B683C4139D66E4DC5"., update "CSS_PRODUCTIVITY"."CENTREDATAASSOCIATIONS_TEST" set "MONTH" = :b1, "TM1_PREMISE_NAME" = :b2,

hi oolite
i can't help you with your problem
but i have one suggestion
i don't know whether you created your tabular form with the wizard or manually
when you use the wizard
i would suggest that you try to build a tabular form manully
in fact it is a little bit more work but i think all what you have done by yourself
is more transparent and errors should be found easier
other suggestions take a look
Error in mru internal routine: Error in MRU
Error in mru internal routine
or search for error on mru
sorry that i can't tell you more

Can update detail record in browse form?

I have a browse form ,it's record do not to create or insert but update,and update only a few column such as change is_disabled to true/false,since then I want change records by click radio group or check box,is this can do?
I use Jdev9.03

I have a simple APEX form based on a table with 2 columns with one column being a primary key.
When i create the APEX form based on my table it hides the primary key column. If I make it visible by changing it to a Text item from Hidden.
I am unable to update or insert a new record in the form. It gives me a MRU error.
I would like to know how can i create my APEX form with both the columns updateable and visible.You didn't provide any information about your apex version, so I assume the most current one (Apex. 4.1).
There you can run the form wizard using the ROWID of your table. If you use that, then the PK column can be filled out manually, just as any other item.

Found the source of the problem. I had hidden the "Row Selector" on the master-detail report (for my purposes it was unneccessary), when re-introduced all was well again.

Master detail form Error in mru internal routine: ORA-20001

Hi,
i created a master-detail form with apex standrad wizard.
Master e datail are on the same page.
All works fine.
My detail form contain some fields of my detail table.
Now i added a link on detail form for call a form with all fields of my detail table.
The link work fine.
When i try to add row or update my detail form i receive the error
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "D472A2BF636CA11122F196B8A32B3DC8", item checksum
Any help?
Thanks in advance
Lukx

Lukx,
I've just reproduced your what I believe you wanted and didn't receive any errors. Here are the steps I took.
1) Used the wizards to create a Master Detail form (with Detail edit on the same page as the master and only showing 2 of the detail columns)
2) Used the wizard to create a FORM ON A TABLE for my detail table allowing the user to edit all detail columns
3) Created a "column link" column on the detail form of the Master Detail form which links to the FORM ON A TABLE, passing across the ID of the detail record.
When I do this, everything seems to work perfectly as expected.
Is there something I'm missing in the steps you performed to create your scenario?
Thanks
Doug

Hi Sam,
You can hide the button very easily without deleting it. Click on the Button in the edit page under the button section. Click on the Condition in the heading tab and change the Condition type attribute to Never. It will never display the button in your page.
Hope this helps.

Error in mru internal routine: ORA-20001: while updating tabular report

Hi,
I am new to APEX..
I am getting the following error when updating a tabular updateable report when I change the query that was created using the wizard.
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process.
I need to get some extra data other than the those returned from the detail table.Hence I have changed the query.
If i delete the row and add a row,no error is displayed.
My primary key has been hidden.
Kindly help.
Thanks .

I had the same problem. When I changed the query then I forgot to add primary key column in the query. That's why I couldn't update the table value. But I could insert a new record bacause I have a trigger at database level to add new id value for primary key column.
