Issue in scheduling /sapsrm/offlineapprovalsend in background

Question

Hello Guys,
My requirement is to send Email to Approver once workitem is send to him in UWL after creation/change of contract. This is not offline approval but just an email specifying to check UWL.
In SRM 7.0 SAP has provided standard program /SAPSRM/OFFLINEAPPROVALSEND. This program sends email correctly to Approvers if correct date and time is mentioned on the screen.
But if I call this program in background through another program, it does not work. Program unables to find workitem in mentioned period since doesnot accept date and time parameters passed in the submit statement. It considers those blank and then internally assign system date and time to it.
Below is the sample code: ( we have also implemented BADI BBP_OFFLINE_APP_BADI to change text )
START-OF-SELECTION.
gv_time  = sy-uzeit.
gv_datum = sy-datum.
to identify workitems which are generated in last 1 hour only
gv_time = gv_time - 3600.
SUBMIT /sapsrm/offlineapprovalsend WITH : p_jobsuf  = '2',
                                          p_bo_ty   = 'BUS2000113',
                                          x_n14all  = c_x,
                                          x_o_html  = c_x,
                                          x_o_dec   = c_x,
                                          x_wi_txt  = c_x,
                                          p_fromd   = gv_datum,
                                          p_fromt   = gv_time,
                                          x_alw_tr  = c_x,
                                          x_prio_2  = c_x .
Kindly help.

Answer 1

Hello,
Reason is I need to change Value of the parameter Date and time on the screen. Contract( workitem) created in last 1 hour need to be executed only.
Date and time on screen work in a way that.. After that particular date and time whatever items are created mail is being send for all those items. Hence I can not keep those constant and should vary at each execution.
