Error in erecruitment after selecting candidate selection

Hi experts,

We are implementing SAP eRecruitmen.In BSP Pages while selecting candidate selection options it is showing dump.

we are getting error like

Error in the ABAP Application Program

The current ABAP program "CL_HRRCF_SES_BUSOBJ_FROM_SPTYPCP" had to be

terminated because it has

come across a statement that unfortunately cannot be executed.

An exception occurred that is explained in detail below.

The exception, which is assigned to class 'CX_SY_CREATE_OBJECT_ERROR', was

caught in

procedure "READ_SPT_INFOCATE_FIELDS" "(METHOD)", nor was it propagated by a

RAISING clause.

Since the caller of the procedure could not have anticipated that the

exception would occur, the current program is terminated.

The reason for the exception is:

The dynamically specified class " " at CREATE OBJECT neither exists as

local, nor as global class in the system, or is overshadowed by a local

data type of the same name.

Need help on this.!!!!!!!

Thanks
