How to put filter on CR type in the BADI USMD_RULE_SERVICE_CROSS_ET

Hi,

I Need to put a filter on CR type in the method 'DERIVE' of BADI USMD_RULE_SERVICE_CROSS_ET.

But I do not find the CR type in this method.

Could you please provide me any other option to get the value of CR type in this method.

Thanks,

Deepa
