- BDC -> Execute the transaction FK02 or XK02 thru recorder transaction SHDB, then use it to generate a sample code (I suggest two recording one for insert one for update)
- VMD_EI_API Method MAINTAIN_BAPI -> There are some sample at scn, use search tool to find documents like Creation of Vendor - VMD_EI_API and some dozen of threads. Look at VENDORS->COMPANY_DATA->COMPANY->WTAX_TYPE.
