CO_TXT_CHANNEL_PASSWORD_ERROR

Hi experts.

I have an interface SOAP to Proxy, but the message processed in PI doesn't arrive in Proxy R3.

The sxi_monitor in R3 side, doesn't have message.

The sxi_monitor in PI side, appear the message below:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

- <!-- Call Adapter

-->

- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">
