Material Reservation BAPI

Question

I'm trying to use the Bapi: BAPI_RESERVATION_CREATE1, but I'm getting the following error:
error '80004004'  Operation aborted
When I use SE37 and fill the RESERVATIONHEADER and RESERVATIONITEMS data I can run the Bapi, but when I fill the same data using an ASP page it doesn't work... I get an error when I call the Bapi.
The ASP code follows bellow;
  Set oBAPI  = CreateObject("SAP.MaterialReservation.1")
  oBAPI.Destination = "XXXXXXXXXXXXXXX"
  'ReservationHeader
  OBapi.DimAs "BapiCreateFromData1", "RESERVATIONHEADER", oResHeader
  oResHeader.AddNew   
  oResHeader.Fields("RES_DATE").Value          = Now
  oResHeader.Fields("MOVE_TYPE").Value          = "001"
  oResHeader.Fields("COSTCENTER").Value          = "00001"
  oResHeader.Update
  'ReservationItems
  OBapi.DimAs "BapiCreateFromData1", "RESERVATIONITEMS", oResItem
  oResItem.AddNew
  oResItem.Fields("MATERIAL").Value          = "XXXXXXXXX"
  oResItem.Fields("PLANT").Value               = "XXXX"
  oResItem.Fields("ENTRY_QNT").Value          = 10
  oResItem.Fields("REQ_DATE").Value          = Now
  oResItem.Update
  ' Result
  OBapi.DimAs "BapiCreateFromData1", "RETURN", oReturn
  ' bapi Call
  oBAPI.BapiCreateFromData1 oResHeader, oResItem, , , oReturn
Does anybody know what might be the problem?

Hi Leonardo,
perhaps you just shortened display, maybe it's a problem:
oResItem.Fields("MATERIAL").Value          = "XXXXXXXXX"
Material number has 18 chars in database. When you enter value via SE37, there is an automatic conversion between display format (without leading zeros) and internal format -> test will work.
If you enter external format via ASP-call, you will not find an article -> use 18 chars.
Have a look at function module 'CONVERSION_EXIT_ALPHA_INPUT' for translation rules (make some tests...).
