<p>The framwork has an built-in pattern to &#8220;freeze&#8221; a record. This is typically useful in accounting type
of applications where a transaction cannot be altered once a subsequent transaction has been made and a
&#8220;posting&#8221; is completed.</p>
<p>In the framework, a record has 3 stages as defined by the property &#8220;docstatus&#8221;</p>
<ul class="simple">
<li>0 - Saved</li>
<li>1 - Submitted (frozen)</li>
<li>2 - Cancelled (or deleted)</li>
</ul>
<p>After cancelling, you can also define an &#8220;Amend&#8221; permission. If the user is allowed to &#8220;Amend&#8221; a
record, a new record is created against the cancelled record with a version number attached.
For example: Invoice IN003 becaomes IN003-1</p>
