security issues

Hi Everybody,

we have two user Groups Sales1& Sales2. here sales1 group belongs to Senior sales Engineer and Sales2 belongs to sales Executives.

and Both Groups are creating sales Quotations by AR-SALES QUOTATION DETAILS. But sales1 Group Engineer asking for  making security to not allow to see (view) Sales2 Group sales Executives  his Quotations.

let me know is it possible or not. my Question is both are using AR-SALES QUOTATION DETAILS to create new Quotations and Generating random Sales Quotations number and viewing list of sales Quotations.How its possible???

thanks & best Regards
