Posted on by GluedTogether

Hi All,

I can't get the "Launch SAP" or "Attach SAP" Actions to run. On The "Attach" Action i get an "Attach to running SAP" error and on the "Launch SAP" i get an "Action failed" error.

This is the error that i get on "Launch SAP"

Correlation Id: b613da2f-83d4-4b8e-85bd-d7b7a16fadfb

Object reference not set to an instance of an object.: Microsoft.PowerPlatform.PowerAutomate.Desktop.Actions.SDK.ActionException: Action failed. ---> System.NullReferenceException: Object reference not set to an instance of an object.

at Microsoft.Flow.RPA.Desktop.Robin.Engine.Execution.ActionRunner.Run(IActionStatement statement, Dictionary`2 inputArguments, Dictionary`2 outputArguments).

Does anyone know how to fix this? Thanks in advance!

Hi @GluedTogether ,

Is your SAP version is higher than or equal to 7.50?
Can you please share the screenshot.

When you tried Attach to running SAP -action did you have SAP open?
Have you tried launching the SAP with Run application -action?

Then if you use Attach SAP when the SAP is open does it work?

Hi @GluedTogether ,

This version appears to be significantly older than the minimum supported range (7.50).
Try launching SAP with Run Application action as shown in below image.

Also try enabling GUI scripting in SAP as shown in below image.

We have the 2022 OnPremise Solution i was able to confirm it:
We also have SAP Logon 800 if that helps any.
When i tried the Attach Action i had SAP fully open and i was logged in. GUI Scripting was already enabled.
The "Run Application" Method starts the SAP Logon App but does nothing afterwards. No Error message either.

Then that sounds like the login credentials are incorrect since it didn't get to login. Make sure that SAPSystemId, Client, user and password are correct.

In the SAP version I use SAPSystemId is three letters and you can find it in the bottom right corner when logged in

Also in the logon screen:

(images are just from google so thats why different environments)

Client, password and User are all like i would type them within the SAP Logon (client saved as a number variable, pw and user as a text). The SystemID is just the 3 Letter Code thats shown on the logon startup app under the SID Column right?

Yes that should be the SystemID. Hmm I'm not sure then what's the issue.

Some people seem to have had problems with newer PAD versions when trying to use SAP.
See: https://powerusers.microsoft.com/t5/Power-Automate-Desktop/Unhandled-Error-Object-Reference-Not-set-to-an-Instance-of-an/td-p/2576010
https://powerusers.microsoft.com/t5/Power-Automate-Desktop/Erro-System-NullReferenceException/m-p/2599399#M36696

So maybe you could try downgrading (or if you don't have the newest version then try updating PAD).
