Moving tab pages automatically in sales quotation line

Hi experts ,

in the sales quotation line we have already around 9 to 10 tab pages (standard ) and we added two tab pages with grid …

(Bom Info , operation Info)

when ever we are adding the line in the Bom Info tab moving automatically to Operation Info tab page in ax 2012…

please suggest me how do this …

Check the data source property of grid/tabs? Do you have separate new button(with action pane) for each tab?
