Hi Varun,
The reason why I asked you to check bbp_backend_dest is that I need to know the system type set for your ECC system.
Then with this system type, you should check if the following entries exist for it in table bbp_function_map.
BBP_FUNCTION_MAP:
BUS1006200 GetVendorData B470_VENDOR_GET_DATA
BUS1006200 GetVendorList2 B46C_VENDOR_GET_LIST2
BUS1006200 GetVendorList3 B46C_VENDOR_GET_LIST3
Best regards,
Ivy
