CHECKING DUPLICATE DATA ON EMPLOYEE RECORD

Hi Folks,

I am using Dynamics nav 2013 and I want a way prevent duplicate

data from being accepted into the employee record when a new entry

is being made. I tried the code below but without success:

BEGIN

  IF emp1.FINDSET THEN

    REPEAT

      emp2.SETRANGE("Social Security No.",emp1."Social Security No.");

      IF emp2.COUNT > 1 THEN

        EXIT(TRUE);

    UNTIL emp1.NEXT = 0;

  EXIT(FALSE);

END;
