Usage of a method in class ADD_ADDITIONAL_FILTERS

Hi frs,

I am working in a CRM Server.

I need to make use of the method ADD_ADDITIONAL_FILTERS in class CL_COM_PRSEARCHSCENARIO_BASE. Since this class is an abstract class we can make use of the class CL_COM_PRSEARCHSCENARIO_GETLST, the same method.

Now the problem is thw method ADD_ADDITIONAL_FILTERS uses IMPORT Parameter "IT_FILTER" which is a associated type COMT_PRSEARCH_FILTER_TAB but this one refers to a interface IF_COM_PRSEARCHFILTER which is having its methods and parameters.

Now how to make use of the method ADD_ADDITIONAL_FILTERS.

Any one is having any inputs.
