Hi Saritha,

I have implemented SAP automation using BAPI calls in Uipath. I can help you if you have any specific queries.
What do you mean by ‘on button click in webpage’? Do you want to start the SAP automation process in the background on a button click?

So If I understand you correctly

you need to trigger the process when a user click on the button which is in webpage

For that you can build a unattended bot with the Bapi activities

Later you need to build the webpage button like onclick using Javascript where you need to use Orchestrator API to trigger the process

Also you can take a look on UiPath Apps also, you can build a form and you can configure onbuttonclick and choose the process

Hope this will help you

Thanks

Hi Sruthi,
Yes thats correct. I need to triggere the bapi and send the response to front end application which would display the status.

Saritha

Hi Srini/Sruthi/Experts

My uipath studio version is 2021.10.4.

After some research I found below 2 accelerators meeting my needs for executing SAP Bapi’s
UiPath Foundation pack for Accelerators for SAP S4HANA
UiPath Accelerator for SAP S4HANA for Basis Administration

I referred to below video for setting it up UiPath SAP Accelerators - Unlock user | SAP S/4HANA | ITSM use-case - YouTube
but am unable to install UiPath.SAP.BAPI.Activities and am getting below error-

As a part of pre-requisites, I have installed both SAP Connectors for 32 bit and 64bit and necessary .net framwork dll.
Can you please advise on how to resolve the above issue?

Thanks,
SK
