Hi All,

As you all know now the power automate desktop has released set of actions for SAP, below is how you can use it to login and work with SAP (SAP 770 or any other SAP windows Application)

We have an action/Activity available as Launch SAP

Put a server description show in SAP connection properties, add user name, password, Language and client as shown below.

In advance you can select whether we need to continue this Logon or Terminate other session etc.

You will be logged into SAP home page.

You can call the transaction with START TRANSACTION action as below

Once you are done with you work you can close as below steps.

You can select the menu items by their names when you Hover the mouse over them for eg: Exit, Back, Save, Print etc

Close SAP connections/Log off

You can do these with VB scripting as well, please give it a try and reach out to me here in case of any concerns. (dwarkabajaj10@gmail.com)

Does your SAP open without problem when you use Launch SAP -action and the 'SAP-Instance' gets stored into %SapInstance% -variable? Can
You need to have SAP Instance so make sure you have used Launch SAP -action and put that %SapInstance% into SAP Instance field in the Start SAP transaction -action.

Then that action failed and there for did not put anything in SapInstance -variable. So then the other actions can't be used since there is no SapInstance(even if SAP seems to have opened).
It shouldn't be empty like in the picture above if your SAP launches correctly from the Launch SAP -action.

Same way like with Excel or Browser actions. There needs to be ExcelInstance variable with it having the instance saved in the instance variable. Like so:

So there is something wrong with your Launch SAP -action. You are certain that all the parameters are correct like Server description and such?

Try using Run application -action to start SAP.

https://learn.microsoft.com/en-us/power-automate/guidance/rpa-sap-playbook/creating-sap-desktop-flow-vbscript

Then try using Attach -action to get the SAP instance variable so you can use SAP -actions.

Also you don't need to use the SAP automation -actions to automate SAP you can just have VBscript that does the actions. Scripting needs to be enabled though.

Can you ask your IT or people who maintain your SAP for help? I think there might be something about the parameters on the backend that makes it difficult for you to login to SAP with the Launch SAP action. Or ask Microsoft support for help.

I had similar issues with one client but fortunately I can use VB scripting with them so run application worked for me.
I noticed that the SAP test environment connection I was trying to get to wasn't listed in the logins System Entry Properties under System ID (Connection Type being Goupr/Server Selection). Even though it is listed in the SAP Logon screen. That might be the issue for me atleast.

I wasn't able to open SAP with Launch SAP on the 05 ECQ connection.
