Try to work within the framework, look at Sidecar (<a href="https://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_10.2/User_Interface/Sidecar/">https://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_10.2/User_Interface/Sidecar/</a>) and SugarBean (<a href="https://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_10.2/Data_Framework/Models/SugarBean/)">support.sugarcrm.com/.../)</a> to start with. They should provide you with what you need to interact with records.</p> <p>Francesca</p><div style="clear:both;"></div>
