A capability should be provided via the Natural API Server to enable cross-machine calls of Natural modules. Similar to EntireX and RPC, this should be possible via CALLNAT using a defined PDA.
If direct communication via the Natural API Server is not available, a REST service currently has to be provided via Natural API on the executing side from the Natural program, and this service then has to be called on the calling side via REQUEST DOCUMENT. This overhead, including field mapping and format transformation, could be avoided if communication could continue to use the interface defined directly in Natural.
| Use Case | Typical use cases for Natural-to-Natural communication in our environment are: Comparison of module timestamps across different environments, Invocation of NOP user exits from applications, for example to start NOP networks and evaluate active NOP runs |
