Cannot find fields in LSMW

Question

hi abap gurus,
i need your help,
this is a Purchase order conversion program, from4.7 to ECC 6.0,
the iput is an excel file which contains the extracted data from 4.7
the structure of the iput file would be
Purchase Req Number  from ECC 6.0  ( EBAN-BANFN )
PR Item     from ECC 6.0                  ( EBAN-BNFPO)
Old PO Number from 4.7                 ( EKKO-EBELN )
Old PO Item from 4.7                       ( EKKO-EBELP)
Vendor                                              ( EKKO-LIFNR )
Material                                            ( EKPO-MATNR).
Quantity                                            ( MENGE-EKPO)
i was asked to do LSMW with a standrd program,
so, i started like this in the first step i chose direst input, with
Object 0085
Method 0001
program # RM06EEI0
program type is D
In the step "Field Mapping & Conversion Rules "
Except for the first two, ie.
Preq Number
PReq item,      i could assign the source fields to the std program fields displayed,
but  i could not find the two fields to map ie, PReq #, Preq Item.
is it that, these two fields are from ECC, i cannot find them in the std prog.
can some one helpme in solving this,
thank you

hi srinivas,
thank you for response,
yes you are right,
it is the first time they are uploading POs, and also they donot have PReqs in system as of now,
but my question is as i am using the std program in lsmw, those filds should appear as target fields in order to map, i am only in the step of mapping, so the error of PReqs not found may be at later stage,
but the std program should show these fileds right?
i think these Preq are bieng used as refernce while creating the POs, in me21
so is this a way, or can we do this way for creating the POs with reference of PReqs
using a std program in LSMW,
or is it a better way to do recording.
