SAP integration process (XI)
A model of the SAP integration process (XI) type represents business processes from the SAP® Exchange Infrastructure.
This kind of business process describes in detail the steps that need to be carried out for exchanging messages between applications.
Each integration process has exactly one start object and one process end.
In the course of the integration process, the following constructs can be created:

Receive

Send

Wait

Block limit (start)

Block limit (end)

Parallelism (start)

Parallelism (end)

Control

Receiver determination

Assignment

Transformation

Switch (start)

Switch (end)

Empty

Loop limit (start)

Loop limit (end)
If the path splits into multiple paths after the start of a block, a parallelism, a switch, or a loop, these paths need to be joined in a corresponding end symbol.
