Hello everyone, Now I have an assignment to explore the Cellular Development Kit. I have followed the tutorial given in the developer sap. At the moment I am developing an application to provide the process of receiving goods, which requires the ability to post data header and items using a single request. Does anyone have a solution for my case? Maybe you have a related case (post header item using mobile development kit), will you share with me how to make it using a mobile development kit? Thank you very much for your response and kindness.
