File to Web Service - No back system in hoplist

[Former Member]

Hi guys

I've implemented a File to Web service Scenario with XI. The file is picked up from the server.

The message monitoring in the Runtime Workbench shows the following error:

"XI-Systemfehler erhalten. ErrorCode: NO_BACK_SYSTEM_IN_HOPLIST ErrorText: ErrorStack: Legacy system to which acknowledgment message is to be sent is missing in hoplist (with wasread=false)"

Has anybody a clue?
