BAPI_PRODORDCONF_CREATE_TT for REVLV

Hi,

I am developing a conversion program. I have a reqiurement where I am getting 5 fields in the flat file out of which one field I am not able to find. i.e REVLV, Revision Level field in the transaction CO11N.

I am using BAPI_PRODORDCONF_CREATE_HDR and BAPI_PRODORDCONF_CREATE_TT. I am not able to find this particular field in both of the BAPIs.

Thanks,

Prasanti
