If bank data can be maintained directly in an infotype (such as theBank Details infotype (0009) and the IBAN button exists for theinfotype, you can also maintain the IBAN for the bank details.
In infotypes such as External Bank Transfers (0011) orMembership Fees (0057), you can or must enter a receiver key fromthe T521B table. If a receiver key is specified, the bank data storedfor the receiver and the related IBAN can be displayed only. It ispossible to maintain bank data and IBAN for the receiver only in theV_521B view. Note that the IBAN is saved in the TIBAN table, and not inthe infotypes or the V_T521B view.
