+<li>Select as many contracts as you want to update line prices.</li>
+<li>Click on Action button and execute the wizard <strong>Create revision of contract
+lines</strong>.</li>
+<li>Enter date start from which the new price will be valid and enter date
+end and percentage to increase old contract lines.</li>
+<li>By clicking on Apply button, a new contract line will be created with
