Hi All,

Iam using SAP logon 800 and power automate 2.46. Iam using run application and attach action of PAD to open the sap server. This works perfectly fine for quality server, but for production server iam getting the below error at attach action:

Exception of type 'Microsoft.Flow.RPA.Desktop.Modules.SAP.Actions.Exceptions.SessionNullException' was thrown.: Microsoft.PowerPlatform.PowerAutomate.Desktop.Actions.SDK.ActionException: Attach to running SAP error Microsoft.Flow.RPA.Desktop.Modules.SAP.Actions.Exceptions.SessionNullException: Exception of type 'Microsoft.Flow.RPA.Desktop.Modules.SAP.Actions.Exceptions.SessionNullException' was thrown.

Hey Rayson-LD,

The error you're encountering, SessionNullException, indicates that Power Automate Desktop is unable to attach to the running SAP session. This issue can be specific to certain configurations or settings in your production server compared to your quality server.

1. Please check the Versions of SAP in both server is same or different.

2. Ensure that no other SAP sessions are interfering with the attach action. Sometimes, multiple open sessions can cause issues.

Hi Sayan,

Thanks for the reply, Really appreciate it.

Following up on your suggestions :

1. How can i check the SAP versions of the servers. Can it be checked in SAP logon 800?

2. Iam sure that there are no other sessions running, Otherwise, the error would've thrown to Quality server as well. But it works fine.

Can you please let me know ...
