I have a multi row form (Order Entry form in E Business Suite). When I enter data in a row and error down the validate-item trigger fires and runs some code to check for duplicates, etc and after the cursor should go down to the next row. It goes back to the original row.

In my form, for an item there is code for pre-text-item trigger. In query mode when i go to next record, previous record etc, whether this trigger gets fired? In other forms it is getting executed. Only in this form it is not getting executed. What should be reason for not executing this pre-text-item? Only this item is enabled and cursor is there.

I have this layout
[URL]
and a post trigger insert and update
IF :item1 IS NULL
AND :item3 IS NOT NULL THEN
alert_id := FIND_ALERT('blank_alert');
SET_ALERT_PROPERTY(alert_id,ALERT_MESSAGE_TEXT,'Item3 must have a value.');
v_alert := SHOW_ALERT(alert_id);
RAISE Form_trigger_Failure;
END IF;
My problem was as it fires, the cursor will be on the item1. I've already use
SET_ITEM_INSTANCE_PROPERTY
NEXT_ITEM
GO_ITEM
but it was all illegal. The cursor must be in the item3.
Don't question me why I do not set the item3 to required and why post triggers. It is just that. It is the requirement.

I am trying to make a particular field (called reason_code) "required" on a form I am working on.
Now this field has two fields before it, and I have to tab to reach my reason_code field.
But the functionality I want is that when I tab into the reason_code field, the WHEN-VALIDATE-ITEM trigger should fire even when this field is NULL.
IF :REASON_CODE IS NULL THEN
MESSAGE ("Please enter a reason code!");
end if;
The trigger doesn't fire when I don't enter a reason_code field and I can tab past this field and not get the ("Please enter a reason code!") error message.
On researching the problem, I saw that this field has to be of status "CHANGED" in order for the trigger to fire.

I have a form w/a tab canvas. BlkA is on Tab1 and Blk2 is on Tab2. In BlkA I have several items that have when-validate-item triggers. However, the trigger does not fire when I enter a value into item1 of BlkA followed by clicking on Tab2. To solve, I placed validate(form_scope) in the When-Tab-Page-Changed trigger. This works well with invoking the validation. However, focus remains on Tab2 (Blk2).
I would like focus to return to failed validation item in Blk1. I can capture the block name using :system.cursor_block in the Post-Block trigger of BlkA, assign that value to a form parameter and when a validation fails via the When-Tab-Page-Changed trigger I can return user back to BlkA(Tab1). However, I need direction on how to return user to the specific item in BlkA that failed validation

I have a form (StaffDetail) with three different blcoks. One of them is an Application Assignment block which consists of nothing but Assignment Type, Staff (Name), Last Updated By and Last Updated Date.. The Assignment Type and Staff has LOVs assigned to them individually.. Assignment type lets me pick all different types except for Project Manager. As soon as I select this option, i get the following error :
FRM-40735: WHEN-VALIDATE-ITEM trigger raised unhandled exception...
This does not even let me select any other Assignment type, then i have to go close all sessions and come back into the same screen.
Also, this form was first created and tested on the development environment and later moved to QA environment. All selections work in the development environment.. I checked for the roles in QA for individual Users..

I am having trouble changing a non-displayed field when a displayed field is changed.
When a user wants to un-assign a territory they want to just null the ID field (non-database item). I then need to null the PIDM field(not visible, database item) for that one record.
I tried this, but I end up putting null on all the records instead of just the one record, which ends up un-assigning all the territories not just the one.
Is there a way to assign the null to the PIDM field associated to the ID field of that particular record.

I have a table with the following data.
item_code item_name
101 Pen
101 Pencil
101 Scale
102 Pen
[Code]...
My aim is to display the missing itemnames for each itemcode.
For each ITEM_CODE there should be four items i.e Pen,Pencil,Scale and Marker If any itemcode missed any of the itemnames those records should display in the output.
So the output should be like this
101 Marker Because the item Marker is missed.
102 Pencil Because the items Pencil and Marker are missed.
102 Marker Because the items Pencil and Marker are missed.
For itemcode 103 no records should be displayed because it having all four itemnames.
