LSMW - Vendor Master DATA - IBAN management

Dear SAP guru's,

I'm trying to integrate the IBAN in vendor master data with my LSMW (batch recording techno).

unfortunately, I do not have the IBAN information in structure BLFBK

BLFBK Vendor Master Record Bank Data (Batch Input Structure)

DO you know how we can integrate an IBAN by LSMW? Batch recording seems to be too risky..

And I do not have the BBAN info, I only receive the IBAN...

Thanks for your comments,

Karim
