You can force the serialization of asynchronous outbound requests for a partner system.
This prevents the "overtaking" effects that can arise when requests are processed in parallel. The following points apply to serial processing:
A follow-up request is not started until the preceding request has terminated.
Serialization includes preprocessing and postprocessing operations but not follow-up processing operations because these are independent of the request.
This function can be used, for example, in a branch-head office configuration in which the branches send multiple files to the head office at the same time (daily, weekly or monthly figures). If serialization is enabled for the partner "head office" in the branch computers then each branch computer can have only one active connection to the head office computer at any one time. This prevents bottlenecks at the head office computer of the sort that occur, for example, if the connection limit is regularly exceeded (see also the CONN-LIM operating parameter).
