Using function module PT_ARQ_REQUEST_EXECUTE to approve leave requests

Question

I'm building a screen to approve or reject multiple leave requests using function module PT_ARQ_REQUEST_EXECUTE as the SAP standard program RPTARQAPP does, and this seems to be working fine.  However, I also need to include a note from the approver which is a bit of long text that ends up in table PTREQ_NOTICE.  This is something that RPTARQAPP does not do.
I cannot find any way of passing this text into PT_ARQ_REQUEST_EXECUTE.  The only way I can find of doing this is to call FM PT_ARQ_REQUEST_PREPARE first (command = PREPARE_APPROVE), update the CURR_NOTICE field it sends back in structure EX_REQUEST, then pass the changed EX_REQUEST structure into FM PT_ARQ_REQUEST_CHECK (command = CHECK_APPROVE)  and then call PT_ARQ_REQUEST_EXECUTE (command = EXECUTE_APPROVE).  This works fine for a single leave request, but when I try to use this process to approve two leave requests the CHECK FM gives me an error on the second record with a message referring to a time conflict with the first message even though the dates on each are not the same.
I've searched and there are a few posts about these FMs, but I still can't fix this problem.  Has anyone ever dealt with this situation before and found a solution?

Answer 1

I've replaced the call to FM PT_ARQ_REQUEST_CHECK with the following and it seems to work pretty well.  Though of course it will need a lot more testing.
STATICS:
    request TYPE REF TO if_pt_req_request.
  CALL METHOD ca_pt_req_header=>agent->get_request
      EXPORTING
        im_request_id     = p_im_request_id
      IMPORTING
        ex_request        = request
      EXCEPTIONS
        request_not_found = 1.
  CALL METHOD request->set_notice
      EXPORTING
        IM_NOTICE               = p_approver_text.
