.. py:method:: set_fields(self, *fields)

**domain**: server

**language**: python

**class** :doc:`Item class </refs/server/item_api>`

Description
===========

Use the ``set_fields`` method to define and store internally the ``fields``
parameter that will be used by the 
:doc:`open <m_open>` 
method, when its own ``fields`` parameter is not specified. The 
:doc:`open <m_open>` 
method clears internally stored parameter value. 

The ``fields`` is arbitrary argument list of field names.

Example
=======

The result of the execution of following code snippets wil be the same:

.. code-block:: py

    item.open(fields=['id', 'invoicedate'])

.. code-block:: py

    item.set_fields('id', 'invoicedate')
    item.open()
