Hello Friends,

This issue is with IDoc -> Webservice interface. The interface is already live and everything is perfect. However few days back, we noticed the nwa logs and we see some metadata related error. The end to end message monitoring shows successful processing of messages without any problem, however nwa log shows following.

Attribute not found: The Adapter Metadata attribute: IDocAdapterStatus is not available for the channel: Channel_Name (IDoc sender channel name).

The Adapter Metadata attribute: IDocAdapterStatus is not available for the channel: CC_SND_IDOC_AAE: 55e165a30e52301eb4a348fd8412cf11
[EXCEPTION]
