Not sure why you're not able to use - py_rollback_pkg.rollback_ass_action
If you have 20 assignments processed for a month - you will have a payroll_action_id and 20 asg_act_ids
rollback_ass_action takes one assignment action and deletes it.
So if you want to delete 10 employee pay runs, then you need to call the below API in a loop.
After the process is successful, you will still see the same Payroll_action_id and 10 asg_act_ids for the remaining 10 employees.
The procedure delte the data from pay_action_interlocks, pay_assignment_actions, pay_run_balances.. for each of the asg_act_id

  NAME
    rollback_ass_action - undo work for assignment action.
  DESCRIPTION
    performs rollback/mark for retry on assignment action.
  NOTES
    This procedure is the entry point to be called to rollback
    or mark for retry an assignment action. On failure, a
    message will be inserted in message lines, indicating that
    the assignment action could not be processed.
    The parameters are used as follows:
      p_payroll_action_id    :
         identifies the row to be processed.
      p_rollback_mode :
         either 'ROLLBACK', 'RETRY' or 'BACKPAY'.
      p_leave_base_table_row :
         if this is true, the procedure does not attempt to update/delete the
         assignment action row. It leaves this to the client. Normally, this
         means a form. However, a message IS inserted by the procedure.
         if false, the procedure update/deletes the assignment action before
         exiting.  Must set this to true if rollback mode is set to 'TRUE'.
      p_all_or_nothing :
         when TRUE, procedure fails immediately if error encountered, otherwise
         processes up to assignment level error limit. Latter is required by
         rollback by assignment set.
      p_dml_mode :
         one of the following:
         'FULL'      : all dml and commits.
         'NO_COMMIT' : all dml, no commit.
         'NONE'      : no dml or commits.
         This allows the user to specify a partial or full validation.
      p_multi_thread :
         this should only be set to true if being called from the
         multi-threaded version of rollback code (i.e. from pyr.lpc).
      p_grp_multi_thread:-
         this is used to indicate which method to maintain the group
         level run balances.  This should be set to true when being
         called from a multi-threaded process. Some multi threaded
         processes use p_multi_thread set to false, hence
         p_grp_multi_thread was created to ensure that all multi threaded
         processes use the correct group run balance deletion.
