Have you tried SET_ITEM_INSTANCE_PROPERTY?

Aha! I forgot that the Enabled property cannot be set at instance level... You can, however, set the update_allowed, insert_allowed, visual attribute. That should be good enough. I created a small example form. I'll attach it. It disables the EMPLOYEE records and turns the items gray when the department_id = 50.

Have a look at it. It runs against the demo user 'HR'.

6i? Do people still use that? It's written in Forms [32 Bit] Version 10.1.2.0.2.

Basically I:
  1. created a block via the block wizard. It's based on HR.EMPLOYEES.
  2. invoked the layout wizard and made the block a multirecord block
  3. added a checkbox (Y/N) just for the fun of having an extra item.
  4. Added an Exit button
  5. Wrote a couple of lines of code. See below.
Here's the content of the PL/SQL code:

WHEN-NEW-FORM-INSTANCE:
Begin
	Execute_Query;
End;
EMPLOYEES.POST-QUERY:
Begin
	If :employees.department_id = 50 THEN
		:employees.chk_test := 'N';
		Disable_Item('employees.chk_test');
		Disable_Item('employees.employee_id');
		Disable_Item('employees.first_name');
		Disable_Item('employees.last_name');
		Disable_Item('employees.department_id');
	End if;
End;
Program unit DISABLE_ITEM
PROCEDURE Disable_Item(p_v_item IN VARCHAR2)
IS
BEGIN
  Set_Item_Instance_Property(p_v_item, current_record, Update_Allowed, Property_False);  
  Set_Item_Instance_Property(p_v_item, current_record, Insert_Allowed, Property_False);
  Set_Item_Instance_Property(p_v_item, current_record, Visual_Attribute, 'VA_DISABLED');
END;
PB_EXIT.WHEN-BUTTON-PRESSED:
Begin
	Exit_Form(No_Validate);
End;

If you want to set attributes for a particular record then do it in the 'pre-record' trigger. For example, turning record level 'delete' 'off'.
