Can anybody explain, how to resolve the following error, which I found in the trace level of response message from BPM. This interface is workin alright in the Dev environment, whereas in QA, the response message is not reaching to the target system but in the XI box it is a black flag. when i drilled down inside the trace level, i found this.
<b> <Trace level="1" type="T">exception while reading from SLD:Exception in SLD client: AbapSLDRequestHandler.execEnumerateInstances(): User credentials are invalid or user is denied access</Trace>
<Trace level="1" type="T">error reading details from SLD for Adapter Engineaf.qxi.sapxitrn</Trace></b>
your help is highly appreciated.
