I don't think A works here, pretty sure it's B since business context is all about controlling which process can use the exception code. D is tempting but that's more about what happens after an exception, not what restricts its use. Anyone disagree?
Not A, it isn't about where you work but B, which process uses the code. I remember seeing business context tied directly to specific warehouse processes, not internal codes or workflows. A feels like a trap since EWM always links exception codes to process steps. I think B is right here-anyone see otherwise?
Pretty sure A is also valid, since CIF is used for data transfer. It handles master data but I think you can use it for documents as well. Not totally confident though, maybe someone else has tested this?
