Hey, link the radio button to a cell to record the selection, i.e. understand in SAP BW is selected or SAP BO. Now take a combo box component and map it to the excel range in the picture you have shared. select insertion type as filtered rows and map the seleted items field to the radio button destination cell(or the cell that tells you what is selected - SAP BW or SAP BO). Map the destination of the combo box to a fresh range in the excel and use this same range as the input for the accordion menu.
According to the selection in the radio button, the values in the accordion menu should change. You may hide the combo box behind the accordion menu itself.
Do let me know if you find the solution helpful.
Thanks,
Prasanna
