How to set a item in a block multirecord at runtime ?

Question

I have a block multirecord and I want just one item block at run time is disabled depends of position the cursor, I used the "set_item_instance" but not got success, as it disables all items of the block and I just want one.
Example: if i rave a data base block in a table "emp," I only want that record number 5, field address is enabled or disabled.

You could have a pre-text-item at block level that checks whether the trigger item and record meet the criteria to be gone into, and if not raise form_trigger_failure.
e.g.
If :system.trigger_item != 'MYBLOCK.ADDRESS' OR
   :system.trigger_record != '5' THEN
    RAISE Form_Trigger_Failure;
END IF;or if it's more complicated than that, write a function
IF NOT valid_item(:system.trigger_record, :system.trigger_item) THEN
  Raise Form_Trigger_Failure;
END IF;
