Hello,
for Shopping Cart, BAdI to change smartform is BBP_CHANGE_SF_SC.
Importing parameters for CHANGE_SMARTFORM method are:
- IV_BUS> in your case, it has to be BUS2121,
- IV_GUID> SC GUID. You can do a GET_DETAIL if you need to check SC data to switch or not to the specific smartform. So, you change the changing parameter SMARTFORM.
Regards.
Laurent.
