Hi,
Assuming your message center execution instance is not the same as your marketing instance (I've seen this too many times), use your marketing instance as a reverse proxy to the message center instance. I.e.:
- SAP calls custom soap interface on marketing instance with model number
- Marketing instance js looks up the number and makes a call to message center exec with the data it collects
- Message center sends message
Step 2 should have user-facing configuration and read the nms:extAccount table for info about exec instances- avoid hardcoding things in general.
Thanks,
-Jon
