Hi Experts,

We want to get a quick solution for how to post a sales return by sanScript code in Dexterity. This is very urgent requirement from our customer. We found a close procedure SOP_Post_TRX in GP 16 SDK. But we don't know what should be passed in the parameter list. because there are some parameters we don't understand what meaning they are. Is there any expert can provide some sample code for how to use the procedure SOP_Post_TRX. It will very helpful for us now.
