Tabular form validation to restrict user

Dear all,
I want to apply the validation on tabular form for my inventory module and I want to restrict the user that the received quantity of particular item should not be greater than the P.O quantity
For example
In P.O
Item Qty
A 20
Received Quantity
Item Qty
A 21
Or if items are received in two shipments like as following
Item Qty
A 10
A 11
I want to put the validation to restrict the user that he can’t save the item quantity more then ordered quantity weather is received partialy or all at once, but I do not understand how can i do that.
I m using Apex 4 with Oracle 11G R2 on windows Server 2003.
Please help
Thanks
Suhaib

Tabular Form Validation - Save Correct Values

I'm using Denes' example of tabular form validation. It finds the errors and displays the error messages, but I lose any values that were entered correctly. Do I need to use a collection to save them? I've been looking through older posts and one comment was that you'd only need a collection if you wanted to show the user the values they entered incorrectly. With Denes' logic it tells them what line had the error and what the original value was.
DECLARE
l_error VARCHAR2 (4000);
BEGIN
 FOR i IN 1 .. apex_application.g_f02.COUNT
 LOOP
 IF NOT TO_DATE (apex_application.g_f05 (i), 'YYYY')
 BETWEEN TRUNC (TO_DATE (apex_application.g_f04 (i),'YYYY'))
 AND TO_DATE ('2008','YYYY') THEN
 l_error := l_error
 || ''
 || 'Row '
 || i
 || ': Photo Inspection Year has to be greater than Date On Map and less than 2008 for '
 || ' Map: '
 || apex_application.g_f02 (i)
 || ' Requested date: '
 || apex_application.g_f05 (i);
 END IF;
 IF NOT TO_DATE (apex_application.g_f04 (i), 'YYYY')
 BETWEEN TO_DATE ('1890','YYYY')
 AND TO_DATE ('2008','YYYY') THEN
 l_error := l_error
 || ''
 || 'Row '
 || i
 || ': Date on map has to be between 1890 and 2008 for '
 || ' Map: '
 || apex_application.g_f02 (i)
 || ' Requested date: '
 || apex_application.g_f04 (i);
 END IF;
 END LOOP;
 RETURN LTRIM (l_error, '');Thanks,
Susan

It doesn't make sense to post your questions within a closed thread - start you own thread.
It is possible to do that but you would need to save your data into a collection to keep the changes and display the error message on the same page.

Tabular Form Validation not working in tabular form APEX 4.0

Hi,
I am using APEX 4.0. I have a tabular form with Tabular form validation done with it.
Item not null is the validation.. so if I dont type any value in the any of the fields in the tabular form and press the Submit button, the first time error is shown... but when I click the Submit button again, with still the empty rows the page is submitted.
How to resolve this issue?

Look at this thread - Re: Validations of tabular forms in 4.0

Tabular Form Validation: Comparing Two Columns vs Check Constraint

What is the best approach for validating that one column needs to be greater than another column in a tabular form when attempting to save. (E.g. An effective date and expirey date column. The expirey date column >= effective date column)
At the moment I have a check constraint on the two columns at the database level which is fine but it returns and passes up a pretty cryptic (from a business user perspective) unfriendly message to the user as follows:
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-02290: check constraint (IDMTC.ADDRESS_TYPE_CON) violated, update "IDMTC"."ADDRESS_TYPE" set "ID" = :b1, "CODE" = :b2, "NAME" = :b3, "LOV_SORT_ORDER" = :b4, "DESCRIPTION" = :b5, "EFFECTIVE_DATE" = :b6, "EXPIRY_DATE" = :b7 where "ID" = :p_pk_col
Unable to process update.
Is there a way to inject, detect and/or replace this with a friendlier business user message? I have confirmed that the "Unable to process update." text at the bottom below the MRU Internal routine error raised from my check constraint is the process error message for my Apply MRU process.
I was hesitating going down a larger page level validation where I loop through the tabular form array and/or inject some client side Javascript.
Any advice? Have I simply overlooked some tabular form options for validating using cross column values?
Thanks,
Jeff

Jeff..Thanks for the response.
However because I am working in a tabular form at design time I don't know which controls I can reference in a dynamic action, or custom Javascript routine other than selecting all elements in a column using JQuery, etc.
I have decided to go with for the time being an approach I found here: doing validation on tabular form
My code ended up looking something like and was entered into a page level validation as a PL/SQL function body returning error text.:
DECLARE
l_error VARCHAR2 (4000);
BEGIN
FOR i IN 1 .. apex_application.g_f02.COUNT
LOOP
--If Expiry date is older then effective date
IF nvl(apex_application.g_f08 (i), to_date('31-DEC-9999', 'dd-mon-yyyy')) < apex_application.g_f07 (i) THEN
l_error :=
l_error
|| ''
|| 'Row '
|| i
|| ': Expiry date must be greater than effective date '
|| ' for maintenance item name: '
|| apex_application.g_f03 (i);
END IF;
END LOOP;
RETURN LTRIM (l_error, '');
END;
I had been hoping with Apex 4+ that there was additional native functionality to do this type of validation or somehow be able to reference a column or control name instead of a generic array column so that my code was better self documenting.
It works for now...but would love to revisit with maybe a cleaner client side solution that does the validation and highlights the invalid element since I still maintain data integrity at the db with the check constraint.
Thanks,
Jeff

Tabular Form Validation Help

Version 2.0
I have a Tabular Form that represents Show dates. There are three displayed fields: Description (Text Field), Date (Date Picker), and Active (Static Select List: Yes;1,No,0).
I need help to create a page validation to make sure that only one show is ACTIVE at a time when the row is submitted.
Thanks,
Joe

On the database side, I use the following technique to implement a "radiobutton" constraint. I think I picked it up from AskTom.
If you have a table like
create table t
show_id int,
show_date varchar2(50),
active_flag varchar2(1),
constraint t#pk primary key (show_id,show_date)
);which is what I think your data model looks like.
You want to ensure that for a given show, only 1 show_date is active (radiobutton-style).
Create the following function-based index on the table
create unique index i on t(decode(active_flag,'Y',show_id));This will prevent invalid data from getting into the table, no matter what.
Regarding your Apex issue, I would suggest that when you add a row to the tabular form, default the select list to Inactive. You can use client-side Javascript to do some toggling of the select lists, but that really assumes that all the rows are being shown in the tabular form. In any case, the unique index above would guarantee data integrity when the data finally hits the database.
Hope this helps.

Tabular form validation(Checkbox) is not working for Interactive report

Hi,
I am using the oracle apex 4.0 and oracle 11g.
I have written a below select query on interactive report as
select
apex_item.checkbox(1,RESIDD)||apex_item.hidden(2,RESIDD) row_selector,
apex_item.text(3,RESNUM) as resnum
from "PDRRES"
and written the validation to display the error message( Function returning error text ) as
DECLARE
vRow BINARY_INTEGER;
BEGIN
-- apex_application.g_print_success_message := NULL;
FOR i IN 1 .. apex_application.g_f01.COUNT
LOOP
vRow := apex_application.g_f01(i);
apex_application.g_print_success_message := apex_application.g_f01(i)||'-'|| apex_application.g_f03(vRow) ;
END LOOP;
END;
Output : No data found error message
As far as it work for sql report with above logic because apex built in row selector
but it fails in case of interactive report for some reason.
Please suggest.

Please suggest.NO DATA FOUND usually occurs when an i mplicit select does not find anything. It can also occur when referencing a collection element that has not been defined.
You have 2 collectinons in the code you posted, apex_application.g_f01() and apex_applciation.g_f03. Since you are looping therough the COUNT attribute of g_f01 its reference ("I") is probably okay and the value store in vRow is probably not right. You can check this by using RAISE_APPLICTION_ERROR to see the value something like
raise_application_error(-20000,'vRow="'||vRo2||'"');Remember that working with checkboxes is tricky. If the box is not checked nothing will be sent. You may need to define a default value when no value is submitted.

Null Validation in Tabular Form in APEX 4.2.2

Hi to all respected Gurus of this Forum!
Recently downloaded APEX 4.2.2. As we know that this version has some improved features and one is the best is i.e. *"Validation on Tabular Form".*
For test purpose I succeeded to apply validation on field of tabular form and I am not allowed to "SUBMIT" data as per Validation Rule.
But now, I want to customize that validation as per below logic.
If required field is null than a message-box should appear with two buttons , as under:
Blank field not allowed. Do you really want to submit? (Buttons should be = YES NO)
If user press "YES" then validation should be false and record should be saved
AND
If user press "NO" then no data should be submitted/inserted as per validation logic.
Please help. Your as usual cooperation is highly appreciated in advance.

Hello Sabine,
>> I read about enhanced validation in 4.1 and would love to get rid of g_f-programming.
The major “trick” is to associate the validation/process with a Tabular Form. On the first screen of both wizards, the first field is Tabular Form. You must select the tabular form on your page (currently there can be only one. In future versions this will change).
Another factor that might influence the behavior of Tabular Form validation/process is the new attribute of Execution Scope. Unfortunately, you must enter Edit mode to gain access to this attribute (i.e., it can’t be set directly from the Tabular Form create wizard). Set it according to your need.
The rest is very simple. You should treat your Tabular Form as a simple form, where every column header stands for a form item. The following is a very simple example of validating the SAL column:
if :SAL < 1500 then
return 'Sal Value is under 1500';
else
return null;
end if;In this validation I’m using the Function Returning Error Text type.

Arie.

Date popup validation in manual tabular form

Hey all-
I'm creating a tabular form manually (i.e., with apex_collection) per instructions at OBE (http://www.oracle.com/technology/products/database/application_express/ppt/odtug2008_marcie_young.pdf). Working fine, except I'm having a problem with apex_item.date_popup.
One of the fields I need to collect from the tabular form is a date. For the SQL report, the relevant item is apex_item.date_popup(9, null, c008, 'YYYY-MM-DD', 20, 10) (and c008 is the relevant column from the collection). The trouble comes in if a user types a bogus date into the date popup. I have validation code to check this, but before running that code, I have to store the user's new entries into the collection. So basically my steps are:
1. display the tabular form w/ a SQL report containing apex_item.date_popup
2. use an update collection PL/SQL process to store the user data into the collection (process point = On Submit and Before Computation)
3. use a validation PL/SQL process to verify the data in the collection before processing the update
All that works, and the validation identifies the bad date. But then the page tries to render the tabular form again (so the user can fix the bad date), but the apex_item.date_popup(9, null, c008, 'YYYY-MM-DD', 20, 10) column fails b/c of the bad date. I need a way to programmatically create a date popup and populate it with (potentially) invalid data. Any ideas?
Thanks
Rob

Problem solved. Tossed the lackluster apex_item.date_popup and replaced w/ jQuery datepicker.

Validation problem on tabular form APEX 4.2

Hi,
My APEX Version is 4.2.
I have problem with validations on tabular forms, for example : I have a column who must be numeric... when I get a character it is controlled properly, but it removes my line of the screen and he writes in the table below:
state error:
ORA-01403: no data found
ORA-06510: PL / SQL: exception defined by the user untreated
I Haven't this problem with this application on APEX 4.0
PS : the validation was automatically create by APEX
Regards

Thomas,
Is this a standard APEX tabular form validation, or a custom PL/SQL based validation? It might be easiest to diagnose what's going on there, if you could replicate this issue on apex.oracle.com, and point us to an example.

Is your validation on the base table or a collection? Denes Kubicek has a couple examples of tabular form validation here:

How to build a tabular form with a by the user insertable primary key

I have build a build a tabular form with the wizzard. Wat should I do to make the primary key insertable by the user.
When I change the PK from 'hidden' to 'text field', I get a checksum error when i am trying to insert.

Fred: When you use the tabular form wizard, notice the help text on the right hand side of each page. The help page where you define the type of primary key (Existing trigger, PL/SQL function, existing sequence) clearly states
Tabular forms do not support user entered primary key values
Makes sense when you think about it. The MRU process needs to determine whether to update a record or insert a new record. It does that by comparing the checksums (and/or) pk values from when the page was first rendered and then when you make changes and submit it. Newly inserted rows will have a blank PK/checksum.
If you allow user to change the PK, how will the system know which rows are new and which ones are old?
For example, lets say you have
create table t
pk int primary key,
data varchar2(10)
)You have 2 rows
1 red
2 yellow
If the PK were to be editable, user could go in and change the above to
2 red
1 yellow
Now what? Would you like the system to create a new row with 1/yellow or change the existing pk=1 row to yellow? Same with the other row.
Bottom line: The built-in processes dont support this. You can always write your own manual tabular form and implement whatever you logic you wish in your After Submit processes.
Hope this helps.

Validate field in tabular forms apex 4.2

Hi.
i need help doing next validations :
1.- i have a product_item field (wich is a lov and user choose one value), so i need to call a function (sending it the selected value product_item) that will return me some data about the product i selected, for example :
if the function return 'A' then
disable the next item on tabular form, lets say quantity
else
enable the next item on tabular form, lets say quantity
end if
2.- i need to determine the result of two items operations:
total := final_quantity - start_quantity
the user will introduce start and final quantity and i will determine the total.
any ideas ?
i am new on apex and need to do this on tabular forms.
thanks in advance.

How to avoid submitting a page when tabular form rows are empty

Hi,
I have a master detail form in my application. There are 2 tables that are used Table A and Table B. Table A contains Ticket number and Table B refers to Table A through a foriegn key and Table B have columns like Date,Name, Age, ticket_id (that refers to the ticket_number of the Table A).
This is how the application works:
In a page there is a field for Ticket Number, once the user enters the Ticket Number and click Add Details, a tabular Form with 5 empty field appears... (Done through Page Process->Data Manipilation->Add Rows)
This form contains fields Date, Name and Age. Once the user fills in all the details and click Submit button, the page is submitted. Whatever values that was entered is saved in Table B. Page Sucess message appears. This works fine.
But once the Ticket Number is entered and Add Details is clicked, and without entering the values in the Tabular Form, if Submit button is clicked, there is no error showing up neither I see Page success message. But this should not be allowed. There should be some error showing up...
Tabular Form Validations works only when user enters some values in the Tabular Form and click Submit. For the above scenario, where the form is untouched the validation doesnt work.
How can I get this done? Any ideas?

Hello Suzi,
>> if (document.wwv_flow==null)
The document.wwv_flow is an object representing the current form that was just rendered on your screen. As such, it can never be null.
>> How to avoid submitting a page when tabular form rows are empty
The correct way, especially for versions prior to APEX 4.0 is to use JavaScript, but for that, you need to know and understand how APEX generates your tabular form, HTML wise.
To be very brief, APEX attached a unique ID to every updatable cell in the tabular form, using a certain pattern – each updatable column is getting a unique name (e.g. ‘f01’,’f02’ etc.) and the ID of a cell is a combination of this name with the serial row number the cell is on. For example, a cell on the third row in an updatable column called ‘f04’ will be given an ID of f04_0003. (More detailed explanation, with an example, can be found in my book).
What you should do is to check these cells according to your validation policy (e.g. is all five row must be filled, is all the columns in a specific row must be filled, etc.).

Arie.

Robert,
I wish I had a better explanation for you, but I know something new with 4.1 broke this union trick for tabular forms. I had to make a dynamic action that runs on page load and calls the addRow() javascript function instead. I think it has something to do with tabular form validation but I am not sure.

How to Testrict Maximum Characters in tabular form

How can I restrict user for maximum character length in tabular form ? in master forms we can define maximum character lenght by using option "Maximum width"
Thanks,
Suhaib

Andy,
I've tried to put the following in my "Element Attributes" of a tabular form "text" element:
maxlength="5" onChange....
A test of the tabular form does not restrict character entry to 5 characters. The page source actually shows both maxlength="2000" and maxlength="3' for the input type tag. It looks as if the first maxlength is used and the maxlength that I added is ignored. It's curious that a tabular form element does not have a "maxlength" attribute to set like a non-tabular form "text" element.
Any suggestions on what else to try?
Alex.
