Issue with a "perform in program" call.

Question

I am trying to do a call to a form in a zprogram. This call is being done inside an enhancement.  The reason for this is because I can't delcare forms in the enhancement.  Below is the issue:
The parameters I am trying to pass are typed as follows (in the SAP enhancement - SAP code):
types: begin of mrm_rbkpv.
        include structure rbkp_v.
types: begin of mmcr_drseg.
        include structure drseg.
types: mmcr_tdrseg type mmcr_drseg occurs 0.
I have the following as the call to the form and the form declaration:
PERFORM cancel_ret IN PROGRAM zcancel_retention USING e_trbkpv e_tdrseg[].
FORM cancel_ret  USING p_tdrseg TYPE rbkp_v
                      it_tdrseG TYPE J_1IDRSEG.
I am getting a run-time error saying:
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_DYN_CALL_ILLEGAL_TYPE', was
     not caught in
    procedure "EXIT_SAPLMRMP_010" "(FUNCTION)", 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:
    Call to FORM "CANCEL_RET" is incorrect:
    The actual parameter no. 1 has a different data type in the
    PERFORM than requested for the FORM "CANCEL_RET" in program
     "ZCANCEL_RETENTION".
This is telling me that the system doesn't see  e_trbkpv being the same type as  p_tdrseg.  However, I can't see why they aren't the same time.  I also assume I will have the issue with the second parameter.  The table type (in my opinion) J_1IDRSEG should be the same type as mmcr_drseg.
Any ideas?  The enhancement I am using is EXIT_SAPLMRMP_010 (LMR1M001).

Aaron

Aaron, I was not aware of the type pools as mentioned I don't have access to the system at the moment. But type pool has type declarations as well, so what I meant was pulling out the 2 declarations that you need into your Z program could have solved the problem :). Which will happen now since you've included the type pools.
Anyways good to know that you problem is solved.
