In transaction <i>SXI_MONITOR</i>, I pull up a list of processed XML messages. When I double-click on one of them, I can view the different versions, and I see the following:
1. Inbound Message (CENTRAL)
2. Receiver Grouping
3. Response
Do all messages have these 3 versions? Do some messages have more or less? If so, in what cases will there be more or less? What does each version correspond to?
