LSMW Standard Batch Input Program

Question

Hi,
I have one requirement on creating BOM.
I have to upload data from legacy system to SAP for T-Code ' CS01'
I have to use the Standard Batch input Program 'RCSBI010'.
I have source structure and Target Structure.
In Source structure i have Header and item data.
In Header i have 11 fields and in Item i have 23 fields.
In Target Structure i have upto 130 fields.
In the Standard program who have 4 structures and each structure have fields.
So How many  fields i have to map with Standard structure. and in my source structure i dont have the fields like T-code, session name, user name,and xkeep.
So how to pass these fields (T-code, session name, user name,and xkeep) to the standard structure. and is it necessary to pass these fields to the standard batch input program.
Advance thanks,
Kumar A

Hi,
    Hi,
Record type 0: one session record (structure BGR00) per session..
The session header contains general administrative data on the batch input session to be created. All records that follow the header in the sequential file are assigned to the current session, until the next header occurs in the file.
Record type 1: one session record (structure BICSK) for each BOM
The BOM header record contains the transaction code (for example, CS01 Create material BOM) and the header data
Record type 2: one item record (structure BICSP) per item
All BOM item records are assigned to the preceding BOM header, until the next BOM header or session header occurs in the sequential file
Record type 3: one sub-item record (structure BICSU) per sub-item
All BOM sub-item records are assigned to the preceding BOM item, until the next item header, BOM header, or session header occurs in the sequential file
and x-line which will be used as index while retreiveing
and the file to be imported should contain values in this format
BGR00 data will be in first line (0-stype)
BICSK in second line (1 stype)
BICSP in 3rd line
BICSU in 4th line
e.g:
0 sessname 800
1 CS01 123
2 values req
3 values req
Hope this gives u some idea...
