Hello @Hamail Saleemi - Based on my understanding, you have created a Logic App and connected a Log Analytics workspace, and you're able to see the workflow logs in the Log Analytics workspace. And next, you now want to send/include your own logging data to a custom table in the same Log Analytics workspace -- is this correct?
If my understanding above is correct, Logic Apps sends its logs to the AzureDiagnostics table in the Log Analytics workspace. The way you can send & include custom data from your workflow runs to this table is by using the TrackingID in trigger settings and TrackedProperties in action settings -- you can specify either a fixed value or use expressions. Here's our official guidance on how to use this feature: Include custom properties in telemetry
I hope this helps. If I misunderstood your question though, just let me know and I'd be happy to assist further.
