Functional module /table vs changing parameter

Question

Hi ,
I am working in release 6.0 .
In program i have internal table and i have to pass it's content to FM. In FM  I tried to declare TABLE parameter but it was not accepted because table parameter is obsolete. I declare Change parameter.  like it was suggested in error message dialog.The parameter is declared after same table like internal table from program .
When I run program I saw that only one record is passed to FM parameter. Question is how to pass whole body content of IT to FM parameter .
Thanks

Hi
See the below example:
types:begin of ty_employee,
pernr type pa0002-pernr,
begda type pa0002-begda,
endda type pa0002-endda,
vorna type pa0002-vorna,
nachn type pa0002-nachn,
end of ty_employee.
*// Declate a types for employee data table
types:tt_employee  type  standard  table  of  ty_employee.
*//Declate a workarea  to hold the Employee data
data: gf_employee     type  ty_employee.
*Declate a table  to hold the Employee data
data: gt_employee     type  tt_employee.
Letz say the gt_employee has 5 records when it is populated.
Then you have all the records of gt_employee when called through below perform in the subroutine.
perform shuffle_records changing gt_employee.
*&      Form  SHUFFLE_RECORDS
      text
     <--P_GT_EMPLOYEE[]  text
form shuffle_records  changing p_gt_employee type tt_employee.
endform.                    " SHUFFLE_RECORDS
