Hi All,
I have one requirement i.e i want to make a particular item as mandatory for the current record in the tabular form.

so i have written code as below:

DECLARE
lv_item item;
BEGIN
lv_item := FIND_ITEM ('XXMZ_DETAIL.QTY_ACT');
SET_ITEM_INSTANCE_PROPERTY (lv_item,
current_record,
required,
property_true);
END;

This code is not effecting qty field.

If i write set_item_property built-in that item becomes mandatory.But it's not effecting at current record level.It's effecting block level.

So how can i make a field as mandatory at current record level?

Please give me some idea.

Thanks,

Code seems to be OK /forum/fa/1600/0/

Which trigger did you put it in?

then it creates a new record

Try to move that code into the WHEN-NEW-RECORD-INSTANCE trigger. Perhaps you'll have to include an IF, such as

if list_item_value = some_value then
   set_item_instance_property
end if

Hi,
I have written the code in the WHEN-NEW-RECORD-INSTANCE trigger using a condition.
If i use set_item_instance_property it's not working.

If i use set_item_propery it's working and in the else part of if we have to make thet property as FALSE.then it's working.

so now my issue is closed

Thank you all..

Thank you very much...

Hi dhanasurya ,
the Item-Property "REQUIRED" only fires, if an item has changed.
You can :
.... MZ_DETAIL.QTY_ACT := 'x'; --( if null before)
SET_ITEM_INSTANCE_PROPERTY (lv_item,current_record,required,property_true); MZ_DETAIL.QTY_ACT := NULL;
or
...
set_item_property(lv_item,IS_VALID,FALSE); SET_ITEM_INSTANCE_PROPERTY (lv_item,current_record,...

But, if you first

SET_ITEM_INSTANCE_PROPERTY (lv_item,current_record,required,property_true);

and then

MZ_DETAIL.QTY_ACT := NULL;

how do you expect it to work?

You have just said "no nulls, please", then you force NULL into the item?

Hi littlefoot,
I assigned a dummy-value i.E.'x' to QTY_ACT, if it is Null,(if "not null" don't make sense), BEFORE! setting Item_instance_property(). It works, the user can NOT leave this item. Seams to been crazy . .. but item-properties are binary and(ed) or or(ed). I don't spend more in this "feature". Because, your code works too (Q: Haven't tested your code; can the user leave the forms-item, after once clicked in?). Because, when an item should be "REQUIRED" the property for the whole column ( in the multi-record) can be set dynamic always again, with "set_item_property", (i.E on When_New-Record/Item-Instance).
