How transfer zfields from BW to R/3

I'm trying do retraction requestions from BW in R/3 using abap prog with funct BAPI_REQUISITION_CREATE. I have also zfields in the table EBAN and I must use structure bapi_te_requisition_item for transfer zfields, but not this structer in BW. How do you want prefer me to do it? I created custom structer ZBAPI_REQUISITION_CREATE but whithout result.

Help me, may be I have error in the code program.
