Hello,

I have a requirement to default first field in detail block and freeze it only the value get defaulted.

I wrote the below code in WHEN NEW REORD INSTANCE trigger.

IF get_block_property('DATA_BLOCLK',CURRENT_RECORD)=1 THEN
SET_ITEM_INSTANCE_PROPERTY('DATA_BLOCK.ITEM',CURRENT_RECORD,UPDATE_ALLOWED,PROPERTY_FALSE);
ELSE
SET_ITEM_INSTANCE_PROPERTY('DATA_BLOCK.ITEM',CURRENT_RECORD,UPDATE_ALLOWED,PROPERTY_TRUE);

This is allowing to freeze the field once it gets saved. But I need to freeze the field as soon as value gets populated.

I aslo tried below code in WHEN_VALIDATE_ITEM

IF :data_block.item1 ='VALUE' THEN
SET_ITEM_INSTANCE_PROPERTY('DATA_BLOCK.ITEM',CURRENT_RECORD,UPDATE_ALLOWED,PROPERTY_FALSE);
ELSE
SET_ITEM_INSTANCE_PROPERTY('DATA_BLOCK.ITEM',CURRENT_RECORD,UPDATE_ALLOWED,PROPERTY_TRUE);
But it does the same thing.

Is there a way to freeze the field as soon a sthe value gets populated??Please suggest

How about this (untested):

-- WHEN-NEW-ITEM-INSTANCE trigger on DATA_BLOCK.ITEM1 item

if :system.trigger_record = '1' then
   :data_block.item1 := 'VALUE';
   next_item;
   set_item_instance_property('data_block.item', current_record, update_allowed, property_false);
end if;

You need to set insert_allowed. It's insert until the record is saved.
