How-to search system logs for BYOD (and other) errors in D365 F&O
In this article I will show how to search the system logs for errors in the running of BYOD jobs. The obvious place to look for error messages is in the Job history of the BYOD job, but sometimes the message there is not detailed enough to understand what caused your job to fail.
Here, I have a BYOD job containing 2 entities, one of which failed. In order to see the error message, I click on “Execution details” in the Job history and then “View execution log”:
In the execution log, there are a few things to look for, the first obviously being the error message itself. However, the error message may be too generic or even non-existent.
You will notice that the Staging status is ‘Ended’ meaning that the staging of the data to be imported in the BYOD job ran without issue, but the Target status is in ‘Error’. This means that the writing of the data into the destination caused the job to error out. The Log text for the Source (i.e. staging) is displayed and tells us that “’154316′ ‘Sales transactions’ record(s) inserted in staging”
Then, by selecting the Target, you can see the Log text for the staging part of the run does not give any details:
So, what do we do now? It is apparent that the Job history does not give us enough details (in this case) to resolve the issue. And we simply cannot do nothing because the error will occur again in the next run of the BYOD job.
Let’s log on to the LCS and look through the raw log files. You may also hear this log referred to as the ‘telemetry log’.
