Launch SAP Action failed

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.Modules.SAP.Actions.SapLogin.Execute(ActionContext context)

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!

The above GUI of SAP which is there in screenshot looks like 740.
SAP server is different and the GUI client which we use is different. You may use any GUI client by getting that installed from your IT.

PAD supports only 750 GUI and above.
https://help.sap.com/docs/sap_gui_for_windows/e8f03b91f99d45f4ae9d90ddf6e44b70/64155e6b9cb84de79ac28...

Once a >= 750 GUI is installed, enable the scripting option in both client & server side.

And that's it! You would be able to automate SAP interface through PAD.

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

eetuRobo_0-1715073174494.png


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.

 

VishnuReddy1997_0-1715073648964.png

 

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

We have the 2022 OnPremise Solution i was able to confirm it: 

GluedTogether_0-1715074089106.png

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.


@GluedTogether wrote:

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

eetuRobo_2-1715079344569.png


Also in the logon screen:

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

@eetuRobo 

GluedTogether_0-1715079302730.png

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? 

GluedTogether_1-1715079463127.png

 

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-...
https://powerusers.microsoft.com/t5/Power-Automate-Desktop/Erro-System-NullReferenceException/m-p/25... 

So maybe you could try downgrading (or if you don't have the newest version then try updating PAD).
downloads for different PAD versions: https://github.com/jfevia/Power-Automate-Desktop/releases 

So I updated to the newest PAD version aswell as Downloading the 4.81 .NET Framework that one comment in your Link talked about. Still the "Launch SAP", "Attach SAP". and "Run Application" all still dont work. Downgrading is not a solution we entertain as we will rather switch to another RPA Solution if this one is incapable of interracting with SAP. 

Sorry to hear those threads didn't offer solution for your issue.

Can you login to SAP from command line without PAD though? I think you might face similar issues with other automation programs if you cant login to SAP from the command line (like Run Application -action is doing).
Try running this from your command line (with your login credentials ofc) and see if that works.

eetuRobo_0-1715161361616.png


I have done many SAP automations to few different SAP versions. Not Hana though. I suggest making a ticket to Microsoft about this and they might be able to either help you or recognize PAD having a bug with your version of SAP and patching it.

Okay i did manage now to start SAP via Run application. (always used the logon.exe and not the sapshcut) But the attach function still doesnt work. But when i use the "Launch SAP" function it also opens the logon.exe and not the sapshcut.exe as it first opens the logon, then opens the system and just stops (And does NOT type anything like user or pw). Wouldnt the "Launch SAP" Function work better if it also just used the sapshcut.exe?

Good to hear that there is progress


Since you said you have scripting enabled could you just use VBScripting to automate the steps you need to do in SAP?
I would then recommend using VBScripts to automate the SAP workflow. So use the SAPs own Script recorder to record all the steps. 

eetuRobo_1-1715173006569.png

Then in PAD use Run VBScript

eetuRobo_0-1715172953496.png


Then just add variables in the VBScript that you have in your PAD.
That's how I've used automating SAP on PAD usually since the SAP actions in PAD are fairly new.

The option for Script recording is greyed out for me but i have it activated within the options menu..

@pradeepvarma 

Thanks alot it works!!!

Btw. When i open SAP Logon the title sais SAP Logon 800 doesnt that mean that i have the GUI 800 version anyway? So i dont need an update?

Yes it means you have the latest version of SAP GUI - which is 800.
