PI 7.31 (single stack) posting RFC gives this error: RFC_ERROR_SYSTEM_FAILURE: Processing of change number CO-01234 cancelled (raised by system ECCHostXYZ)

I'm trying to determine if I am dealing with an RFC connection issue or just an error resulting from the RFC itself.

The error says "Processing of change number...cancelled (raised by...ECCHostXYZ)".

I thought this was a problem with my RFC config because it is labeled as "RFC_ERROR_SYSTEM_FAILURE".

However, when I google that specific message, it appears to be an error specific to change order creation.

Here’s my google search: http://goo.gl/ZhKsm3

Here is the error again:

RFC_ERROR_SYSTEM_FAILURE: Processing of change number CO-01234 cancelled (raised by system ED1|ecc-host-xyz)

When I check ST22, I see no RFC errors.
