Problem with triggers

An Oracle 8 application isn't working apparently because the triggers are messed up. How can I fix this?

There are a number of ways to do this.
The simplest is to keep an extra column on each table that indicates which table a record originated in. Check this column in your triggers to prevent looping.
Other options would include package variables that you could set or using a third table as a variable.
But the real question, I think, is what you are attempting to do. It seems to me that you are implementing a mutli-master replication system. It is much easier to synchronize two-tables by using Oracle's built-in replication features than it will be by hand.

Problem with triggering process chain

Hi
We have a remote process chain that calls a process chain in another system.The process chain in the other system is not getting triggered with the remote chain.
We have 3 such remote chains and we are facing such a problem with only one of them.
The process chain in the other system has a start variant which gets triggered( i suppose) and gives an instance id...the next step in the process chain is to load data into a ODS.Now this step remains yellow forever.When i manually try to schedule this step it gives me records and the request in the monitor screen turns green.But the process chain step continues to remain yellow.
What can be a way out for triggering the process chain or where could the problem be?
Please help
Thanks,
Suchi

Hi Suchitra,
Even though ur process seems to be in yellow your data loading may be completed and the reason for it may be the delay in activation of ODs by ur PC.
For your information please go through the below infm provided in SAp Library
Note when loading into an ODS object and for the subsequent, event-controlled update:
If you switched on the automatic activation in the ODS maintenance or administration, the monitor status for the request remains yellow after the load was successfully completed. Nevertheless, the subsequent processing for the InfoPackage is started, because the loading process is successfully completed.

Weird Problem with triggers

Hi All,
I am facing a problem which now I am finding difficult to get to the root cause.
I have a trigger which inserts a row in a table whenever a column is updated in a table or a new row(s) gets added in the table.However , for update it checks that the updated value should be different from the existing value, if yes, then only it inserts in the Audit table.
For some reasons I can see same rows in the Audit table with same column values based on applying CreatedOn Desc.
Table Schema :(deliberately made small for demo)
CREATE TABLE Relationship
RelationshipID INT NOT NULL PRIMARY KEY ,
ProfileStageID INT NOT NULL ,
CreatedBy VARCHAR(128) NOT NULL,
CreatedOn DATETIME NOT NULL
GO
ALTER TRIGGER [dbo].[Relationship_AuditProfileStageProgress] ON [dbo].[Relationship]
AFTER INSERT,UPDATE
AS
IF UPDATE(ProfileStageID) AND EXISTS (SELECT * FROM inserted I INNER JOIN deleted D ON I.ProfileStageID <> D.ProfileStageID AND I.RelationshipID = D.RelationShipID)
BEGIN
INSERT INTO ProfileStageProgress(ProfileStageID,RelationshipID,CreatedBy,CreatedOn)
SELECT ProfileStageID,RelationshipID,UpdatedBy,GETDATE() FROM INSERTED
END
IF EXISTS (SELECT * FROM INSERTED) AND NOT EXISTS (SELECT * FROM DELETED)
BEGIN
INSERT INTO ProfileStageProgress(ProfileStageID,RelationshipID,CreatedBy,CreatedOn)
SELECT ProfileStageID,RelationshipID,CreatedBy,GETDATE() FROM INSERTED
END
This is the sample data which is indeed incorrect based on trigger definition :
ProfileStageProgressID
ProfileStageID
RelationshipID CreatedBy
CreatedOn

Can anybody give me some insight of what may be happening here.
Thanks
Thanks and regards, Rishabh K

reason is you're just checking that condition outside using EXISTS so even if there's atleast one record in update with different value it become true and will insert all records from INSERTED. I think what you want is this ie checking condition at the time
of insert
ALTER TRIGGER [dbo].[Relationship_AuditProfileStageProgress] ON [dbo].[Relationship]
AFTER INSERT,UPDATE
AS
IF UPDATE(ProfileStageID) AND EXISTS (SELECT * FROM inserted I INNER JOIN deleted D ON I.ProfileStageID <> D.ProfileStageID AND I.RelationshipID = D.RelationShipID)
BEGIN
INSERT INTO ProfileStageProgress(ProfileStageID,RelationshipID,CreatedBy,CreatedOn)
SELECT ProfileStageID,RelationshipID,UpdatedBy,GETDATE()
FROM INSERTED i
WHERE EXISTS (SELECT 1
FROM DELETED D
WHERE I.ProfileStageID <> D.ProfileStageID AND I.RelationshipID = D.RelationShipID
END
IF EXISTS (SELECT * FROM INSERTED) AND NOT EXISTS (SELECT * FROM DELETED)
BEGIN
INSERT INTO ProfileStageProgress(ProfileStageID,RelationshipID,CreatedBy,CreatedOn)
SELECT ProfileStageID,RelationshipID,CreatedBy,GETDATE() FROM INSERTED
END

Simple problem with triggers

Hi all,
Initially I have written a trigger for testing .But im not able to write it as per the requirement.Actually I have written the trigger for a table "test" when a row is inserted into it then my trigger will insert a row in another table.In the same way if an row is UPDATED then that same field of the same row is to be updated in another table.how can I do this by modifying this trigger code.Im in a confusion of doing this.
Table: test.
Name Null? Type
ID NOT NULL NUMBER(38)
UNAME VARCHAR2(15)
PWD VARCHAR2(10)
Table : test123.
Name Null? Type
ID NUMBER
UNAME VARCHAR2(30)
PWD VARCHAR2(30)
the trigger is as follows:
CREATE OR REPLACE TRIGGER inst_trigger
AFTER INSERT OR UPDATE
ON test
FOR EACH ROW
DECLARE
     id number;
     uname varchar2(20);
     pwd varchar2(20);
BEGIN
     id := 1245;
     uname :='abc';
     pwd := 'xyz';
     IF INSERTING THEN
INSERT INTO test123 VALUES (id,uname,pwd);
     END IF;
END test_trigger;
how can i modify this for the above mentioned use.
Thanks in advance,
Trinath Somanchi,
Hyderabad.

Hallo,
naturally , you have not assign values directly in trigger. They come automatically
in trigger with :new - variables.
CREATE OR REPLACE TRIGGER scott.inst_trigger
AFTER INSERT OR UPDATE
ON scott.test
FOR EACH ROW
BEGIN
IF INSERTING THEN
INSERT INTO scott.test123 VALUES (:new.id,:new.uname,:new.pwd);
ELSE
UPDATE scott.test123
set uname = :new.uname, pwd = :new.pwd
where id = :new.id;
END IF;
END inst_trigger;Nicolas, yes, merge here is very effective, but i think, that OP can starts with simpler version von "upsert".

I have problems with triggers

Hi,
I want to do this: When a signal reaches an established level, the trigger act and begins the recording data during a time.
So, im trying to use a trigger fixing a positive value. But the recording data begins when I start the measurement.(clicking the run button).
How could I do what i wish?
Other question.
Is possible to record data when the signal reaches a level and stop the recording when the signal value dicrease? How can I do that?
Thanks a lot.

Hi jcastan,
The answer to the first of your answers is yes, you should be able to do that.
Try to configure your task as it appears in the attached snapshot
"trigger.jpg", just change the triggering value according to your application. It should work, in my case I've wired a square
waveform to channel no.1 and I am using it to trigger the task.
The answer to your second question is a litlle bit more tricky, first try to add a Limit
test (see snapshot "test.jpg"). It is a quite straight forward
implementation but it may work, in my simple case it showed to behave
correctly. Test it and let me know if it worked.
Hope
you found it helpful.
Best.

Intersecting problem with two triggers

Hello to all professionalists.
Today I have got a very big problem with triggers.
I have written an historical function for the application we use. This historical function works while it created triggers on every table that should be audited. There are some specialities like auditing on individual columns but the main reason is the following:
for each table the auditing is turned on every value that is changed should be written with old and new value to a history Table.
This works fine except that when there is another trigger on that table (BEFORE ....ROW) that does an UPDATE on another table. Then the auditing is not working as expected. Well, it isn't working at all for that table.
So my question is if you have had the same experience or if you could tell me some workaround.
Thank you very, very much
Henrik Rünger

I found the fix, go to System Preferences and open Mission Control and uncheck the box to keep monitors as they were (When switching to an application...........)

Problem with Roles and Triggers

I'm having a strange problem with Roles and Triggers in Oracle. It's a little difficult to describe, so bear with me...
I'm trying to create a trigger that inserts records into a table belonging to a different user/owner. Of course, the owner of this trigger needs rights to insert records into this other table. I find that if I add these rights directly to the owner of the trigger, everything works okay and the trigger compiles successfully.
However, if I first create a Role and grant the "insert" rights to it, and then assign this role to the owner of the trigger, the trigger does not compile successfully.
To illustrate this, here's an example script. I'm using Oracle 10g Release 2...
-- Clean up...
DROP TABLE TestUser.TrigTable;
DROP TABLE TestUser2.TestTable;
DROP ROLE TestRole;
DROP TRIGGER TestUser.TestTrigger;
DROP USER TestUser CASCADE;
DROP USER TestUser2 CASCADE;
-- Create Users...
CREATE USER TestUser IDENTIFIED BY password DEFAULT TABLESPACE "USERS" TEMPORARY TABLESPACE "TEMP" QUOTA UNLIMITED ON "USERS";
CREATE USER TestUser2 IDENTIFIED BY password DEFAULT TABLESPACE "USERS" TEMPORARY TABLESPACE "TEMP" QUOTA UNLIMITED ON "USERS";
CREATE TABLE TestUser.TrigTable (TestColumn VARCHAR2(40));
CREATE TABLE TestUser2.TestTable (TestColumn VARCHAR2(40));
-- Grant Insert rights on TestTable to TestRole...
CREATE ROLE TestRole NOT IDENTIFIED;
GRANT INSERT ON TestUser2.TestTable TO TestRole;
-- Add TestRole to TestUser. TestUser should now have rights to INSERT on TestTable
GRANT TestRole TO TestUser;
ALTER USER TestUser DEFAULT ROLE ALL;
-- Now, create the trigger. This compiles unsuccessfully...
CREATE TRIGGER TestUser.TestTrigger AFTER INSERT ON TestUser.TrigTable
BEGIN
INSERT INTO TestUser2.TestTable (TestColumn) VALUES ('Test');
END;
When I do a "SHOW ERRORS;" after this, I get:
SQL> show errors;
Errors for TRIGGER TESTUSER.TESTTRIGGER:
LINE/COL ERROR
2/3 PL/SQL: SQL Statement ignored
2/25 PL/SQL: ORA-00942: table or view does not exist
SQL>
As I said above, if I just add the Insert rights directly to TestUser, the trigger compiles perfectly. Does anyone know why this is happening?
Thanks!
Adrian

Hi Raghu,
If the insert rights exist only on TestRole, and TestRole is assigned to TestUser, I can do the INSERT statement you suggest with no problems if I just execute it from SQLPlus (logged in as TestUser).
The question is, why does the same INSERT fail when it's inside the trigger?

I’m having an intermittent problem with my midi controllers triggering Mainstage 3.
I’m using a PreSonus Firebox audio interface.
It’s been working fine for months, but now when I first turn on the computer in the morning , I’m not able to trigger MainStage from the keyboard. I tried different midi controllers, different keyboards, different midi cords, and check midi preferences. The audio interface is working fine and is recogonized, but the midi doesn’twork. I re-started the computer several times and then finally it miraculously starts working again.
I’ve been having to this every day now. Any help or ideas is very much appreciated.

I Had the same problem with a FireStudio. Try unplugging the FireWire plug and the power plug. Wait for a few seconds, then plug both back in. The light on my FireStudio was flashing blue/red which means "not connecting." I did what I just described, and everything works again. Hope it works for you.

Problem with two of my business rule triggers

Good morning every one,
I have a small problem with two of my business rule triggers.
I have these tables:
pms_activity
csh_cash
csh_integrate_leh
csh_integrate_led
and my process goes like this:
upon approval of a row in my pms_activity table I have a trigger that insert a row in my csh_cash - and in the csh_cash table I have a trigger that will insert in the csh_ingerate_leh and csh_integrate_led.
my problem is pms_activity does generate a row in csh_cash but the trigger in the cash does not fire to generate a row in the csh_integrate_leh and led tables.
I have generated in the following order after I created my business rule:
I have generated the table from the designer (server module tab)
I have generated the CAPI from the head start utility
I have generated the API from the designer
I have generated the CAPI from the designer
I have run the recompil.sql
I have checked that my business rule trigger is enabled and should run on insert and no where restriction
=== this is my business rule logic ======
l_rule_ok boolean := true;
begin
trace('br_csh001_cev (f)');
csh_gl_pkg.csh_gen_integ_jvs(p_id

Any help will be appreciated as I have struggled with this for two days.
Thanks

Try resetting it again and restoring with the same backup file...
Does the phone work properly once you've reset it before you try restoring? A lot of people here have experienced problems restoring from backups... could be worth forgetting about it and starting from scratch.
You could try contacting your nearest Nokia Service Centre (www.nokia.com/repair) and see if they can do anything - it may need the firmware reinstalling or upgrading... possibly... give them a call though and see.

URGENT! Problems with On-Commit and Key-Commit triggers!!

Hi there,
We are having a problem with our form actually saving a value to the database after the commit_form is given.
When we hit the Save Button (which triggers the Key-Commit, and that in turn triggers the On-Commit trigger) we want a populated global variable to save to the database. Now when we hit Save, we can see the field get populated properly with this Global Variable (Global.Last_Tckt_Read), BUT it doesn't save to the database.
Here is the code from the On-Commit trigger:
IF :cg$bf_meter.closing_ticket_issued = 'N'
THEN
:CG$bf_meter.opening_meter_reading := :GLOBAL.LAST_TCKT_READ;
:CG$bf_meter.opening_meter_reading_date := :GLOBAL.LAST_TCKT_DATE;
:CG$bf_meter.closing_meter_reading_date := :CG$bf_meter.last_ticket_date;
:GLOBAL.PREV_METER_READING := :CG$BF_METER.LAST_TICKET_READING;
:GLOBAL.WINDOW_ACTIVE_CHECK := 'true';
:GLOBAL.FTDAYCHM_SAVED := 'true';
commit_form;
ELSE
:GLOBAL.PREV_METER_READING := :CG$BF_METER.LAST_TICKET_READING;
:GLOBAL.WINDOW_ACTIVE_CHECK := 'true';
:GLOBAL.FTDAYCHM_SAVED := 'true';
commit_form;
END IF;
The code in the Key-Commit trigger is just commit_form;. Now, the code from the On-Commit seems to work fine if its in the Key-Commit trigger -- BUT we need to use the On-Commit in case the user exits the Form with the Exit Button on the toolbar or "X" on the title bar (Neither the Exit Button and the "X" will call the Key-Commit trigger).
Any ideas how we can get this data value to actually SAVE in the database??
Thanks for any help -- please respond, this deadline has already passed!
Mike

Well, I can't say I understand what you want, but:
1) if you have only commit_form in key-commit - then you do not need this trigger. key-commit will fire when F10 (commit) is pressed, but since it is doing the same - there is no need.
2) why don't you populate your block values to be saved right in SAVE button trigger and issue commit_form in the same trigger?
Then you can have key-commit to cover the same functionality for F10 with code:
go_item('save');
execute_trigger('when-button-pressed');
3) I cannot get the point of the "close" stuff - on close you want to check for changes or not? and to allow the user to exit with or without saving?

Triggering problems with IMAQ PCI 1411 using NI-IMAQ 2.6 drivers

I am having problems with the NI-IMAQ triggering mechanisms. I would like to use imgSessionWaitSignalAsync to register a call-back function to be repeatedly called on rising edges on the external trigger line. Now the external trigger line is connected to a photocell that is low when there are no objects in front of it and is high when there is an object in front of it. Unfortunately, when running my application, the callback function is not always triggered when an object moves in front of the photocell, and it is often triggered when no object is in front of the photocell. The callback function is not called anywhere else in the code.
An engineer at my company hooked up an oscilloscope to the trigger l
ine and we found that the photocell performs as expected. So I am looking for help to ensure that every time an object starts to pass in front of the photocell, the callback function will be triggered.
System Details:
Windows 2000 PC
Visual C++ 6.0
2x IMAQ PCI 1411 installed(one is revision A, the other is revision C.) I have the same problem even if I switch to the other card.
NI-IMAQ 2.60.0 drivers
Thanks in advance,
Michael

Bruce,
In fact that was my problem. The XC-73 operates at 30 Hz. My strobe
lighting was not triggered at 30 Hz. Once they matched, the

Problems with IP Phones registration to CUCME on SG200-50P

Problems with IP Phones registration to CUCME on SG200-50P
System setup:
- Router Cisco 2811 with IOS 12.4(24)T5 Advanced IP Services, CUCME 7.1, DHCP Server
   with HWIC-4ESW
- Switches:
   - old - SLM224P
   - new - SG200-50P (SLM2048PT), OS v1.3.2.02
- IP Phones 7911 and 7931, OS v8.4.2
One VLAN (for desktops and IP Phones) and one IP subnet, no voice VLAN.
Network diagram:
C2811---HWIC-4ESW---SWITCH---IPPhones
Problem description:
1. In the old setup with SLM224P everything works fine.
   Connected phones almost immediately (1-2 sec. after power up) get ip address, configuration and registers to CUCME.
2. When switch is changed to new SG200-50G:
   - ip phones get their ip address and tftp configuration very slowly - about 10-20 seconds
   - ip phones cant register to CUCME at all. On the router with SCCP debugging turned on there is no sing of registration attempt
   - after reconnecting the old SLM224P situation backs to normal
Things that have been checked or tried without success:
- ports speed and duplex auto, correct detection - although not tested with manual settings
- CDP/LLDP on/off
- smartport mode auto and most static settings, also with disabled smartport
- power cycle / reset
- spanning tree and port security settings
- solutions from that post - https://supportforums.cisco.com/thread/2232161
None of the above methods worked.
The only action that allowed ip phones to register was changing smartport role to static IPPhone + Desktop.
After that when phone was disconnected and then reconnected the problem exists again - no registration (IP Phone status DECEASED in CUCME). Same with power cycle/reset.
Please advice.
Thanks in advance.

1 - You have created the voice vlan?
Nope, flat network, one ip subnet (10 hosts and 10 phones)
2 - Have you set a phone on an untagged access port for the voice vlan to see if it works?
Yep, phones are connected to untagged access ports of the one and only vlan
3 - Have you tried to set the auto voice vlan on the switch so it dynamically assigns the role for ip phone + desktop?
Not sure about auto voice vlan setting, although there was no triggers to AVV - no static voice vlan, no CDP/VSDP advertisements of voice vlan.
We've tested static and auto smartport roles (independently of auto voice vlan feature) with successful auto-detection.
The switch was pretty much in default out-of-the-box config (beside management parameters).
4 - When rebooting the switch, you did ensure to save the start up to running config?
Yes, running to startup
5 - Have you manually set spanning tree PORT FAST for the phone ports?
No, we haven't tested that. But portfast should be set automatically for the desktop and ip phone smartport roles.

Problem with dynamic LOV and function

Hello all!
I'm having a problem with a dynamic lov in APEX 3.0.1.00.08. Hope you can help me!
I have Report and Form application. On the Form page i have a Page Item (Popup Key LOV (Displays description, returns key value)).
When i submit the sql code in the 'List of vaules defention' box. I get the following message;
1 error has occurred
LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query.
When i excecute the code below in TOAD or in the SQL Workshop it returns the values i want to see. But somehow APEX doesn't like the sql....
SELECT REC_OMSCHRIJVING d, REC_DNS_ID r FROM
TABLE(CAST(return_dns_lov_fn(:P2_DNS_ID) AS dns_table_type)) order by 1
returns_dns_lov_fn is a function, code is below;
CREATE OR REPLACE FUNCTION DRSSYS.return_dns_lov_fn (p2_dns_id number)
RETURN dns_table_type
AS
v_data dns_table_type := dns_table_type ();
BEGIN
IF p2_dns_id = 2
THEN
FOR c IN (SELECT dns_id dns, omschrijving oms

and the types;
CREATE OR REPLACE TYPE DRSSYS.dns_rectype AS OBJECT (rec_dns_id NUMBER, rec_omschrijving VARCHAR2(255));

I just had the same problem when I used a function in a where clause.
I have a function that checks if the current user has acces or not (returning varchar 'Y' or 'N').
In where clause I have this:
where myFunction(:user, somePK) = 'Y'
It seems that when APEX checked if my query was valid, my function triggered and exception.
As Varad pointed out, check for exception that could be triggered by a null 'p2_dns_id'
Hope that helped you out.

Problem with set_item_instance_property and set_lov_property

Hello guys,
I am using oracle forms 6i and new to it. I am having a multi data block.
I am facing a problem when I try to set the item instance property with respect to the list type.
1) Basically, I am having a list item having three types MANUAL, INVOICE and BOE. All are independent of each other. I am facing the problem with the MANUAL type.
I have written this code on When-Validate-Trigger of the list item as well as When-List-Changed. Also I am not setting the properties of any items initially(neither on When-New-Form-Instance nor on When-New-Block-Instance).
if block.doc_type = 'MANUAL' then
set_item_instance_property('BLOCK.VENDOR_NO', to_number(:system.cursor_record), REQUIRED,PROPERTY_TRUE);
end if;
But I am getting this warning/error frm 41383 - no such property for set_item_instance_property on both the triggers for the first time when I open the form and thereafter. During the same form session, if I click on the next line it shows a message Field cannot be empty and directs to the item where I compulsory need to insert a value. I also tried using to_number(:system.trigger_record) but getting the same issue. There are many more items I need to set the same property for.
2)The invoice item on the block/form has a LOV. Another requirement is when I select 'MANUAL' , that LOV should not appear on selection of 'MANUAL' type and the user should be able to insert the value manually and validate manually. I did use set_lov_property, but did not get the correct usage. Please assist as soon as you can.

Just out of my interest I would like to know what you exactly meant by "The :SYSTEM.CURSOR_RECORD reflects where the navigation cursor is; which could be different from the record that is initiating the event." in your reply.If you look at the Forms Help for both objects, you will see that...
SYSTEM.CURSOR_RECORD represents the number of the record where the cursor is located. This number represents the record's current physical order in the block's list of records. The value is always a character string.
SYSTEM.TRIGGER_RECORD represents the number of the record that Form Builder is processing. This number represents the record's current physical order in the block's list of records. The value is always a character string. Through PL/SQL you can send (using the GO_ITEM, GO_BLOCK and GO_RECORD built-ins) the interenal Forms Cursor to a different item, block or record within the current block. If, you GO to a different block or record in the same body of code and you then evaluated the :SYSTEM.CURSOR_RECORD and compared it with the :SYSTEM.TRIGGER_RECORD you would find that they are generally different.
2) In response to the second one, do you want to say that when it I select MANUAL I do not use the set_item_property OR use this property and attach an LOV which does not return anything OR use this property, give the name of the same of the same LOV,I am using and set PROPERTY_FALSE. First a litte back ground. When an Item has an LOV assigned to it, Oracle Forms automatically displays what it calls the "LOV List Lamp" in the status bar. With Forms 9i and higher, it displays and "List of Valu..." in the status bar when an item has an LOV assigned to it. Items can have an LOV assigned during design-time or during run-time. You cannot, however, unassign an LOV during Run-time becuase the SET_ITEM_PROPERTY built-in requires you to pass a valid LOV object name.
Well, as I was writing this, it occured to me that you will not be able to set the LOV assigned to your multi-row item at run-time either because once you assign an LOV to an item in a multi-row block, all occurances of the Item will have the LOV assigned. This being the case, I would recommend using a button and give it the appearance of enabled or disabled by using the VISUAL_ATTRIBUTE property and add code to the button so that if the row status is MANUAL then nothing happens. Using this method, you would create two Visual Attribute (VA) objects; ENABLED and DISABLED. The ENABLED VA would make the button look like a normal button while the DISABLED VA would make the button look like it is disabled (grey out button text, etc).
I would also like to know when to use set_lov_property and if you could explain in brief with an example.The only time I have used the SET_LOV_PROPERTY() built-in is when I needed to change the Record Group query assigned to the LOV. We have a form where depending on the "Action" selected, the LOV for a certain item needed to change. The values returned by the LOV were still assigned to the same block items, so rather than create multiple LOVs and set the Column Mapping for each LOV, I just create a Record Group object for each action and then used the SET_LOV_PROPERTY() built-in to change the LOV TITLE and GROUP_NAME. This way, I was able to reuse the LOV and it's existing column mappings while changing the record group that provided the data for the LOV.
The problem lies when I am entering the fields after the invoice number. The fields before the invoice no including the field of invoice no hold the value entered but when I click/press a tab key to go on to the next field the values in the earlier fields(i.e fields before invoice no and invoice no field) disappear i.e. the values do not hold their place and again prompts me from start to enter the vendor no.Are you navigating to a new row/record? That could explain the disappearing data. If not, then I would look for a trigger on the item you're navigating too or for a Block level When-New-Item-Instance trigger that has code that sets the items to null. It sounds like something in the design is causing the field values to disappear (get set to NULL) so I would look at what happens in your form when a navigation event occurs.
@Andreas - actually, REQUIRED is a valid property for the Set-Item-Instance-Property() built-in. ;)
Hope this helps,
Craig...
