Need an expert freelancer to help solve our ongoing issues with ATG 11.2. As part of our development changes we are facing some issues with removing promotion from ATG CRS store. Promotion removal is working fine at server side but same is not reflecting in client UI. Communication and attention to detail is important. So, please start your proposal with phrase "one small step" so that I know you have understood the requirements. At ATG server side logs, we can see promotion is removed from current order, but somehow it's not reflecting in users shopping cart at CRS UI. You need to know the following to complete this work. - One must have an expert level understanding of ATG serverside development for store. - You must know how pricing and promotions work in ATG store. This should not be more than 3 hrs of work.
