Hi @Saul_Antonio_Valdez_Lopez
To be able to understand your automation challenge better, please share following information:

  • SAP WinGUI version
  • SAP WinGUI transaction
  • UiPath Studio version
  • UiPath UiAutomation Activity version

In addition share the following screenshots:

  • SAP WinGUI screenshot - Full screen (you can blurry the business information)
  • SAP UiPath Studio - selectors of SAP element

Best regards, Lev

I would definitely not use any Anchors or any Find Elements - this is not needed, as you are using SAP Scripting interface and UiPath can automate all with stable and reliable selectors.

use simple Click Activity and we will click the right checkbox.

If you have to select more elements, then use CTRL+CLICK, the same as Human-being would do it.

Best regards, Lev
