Hi Satish,
I have already checked the conversion for bank account number.
for vmd_ei_api=>maintain_bapi , the structure is as below
VMDS_EI_MAIN-->VMDS_EI_EXTERN-->VMDS_EI_CENTRAL_DATA-->CVIS_EI_BANKDETAIL-->CVIS_EI_BANKDETAIL_KEY
Here in the above Bankdetail_key structure consists of BANKS,BANKL,BANKN fields as key fields.
I need to update BANKN - acct number with the same BNAKS & BANKL .
Which is happening while creating vendor via XK01 tcode.
Regards,
Lokeswar Reddy Byni.
