We have a SWIFT key field in the Bank section for the BP data model which is read only field from the MDG perspective but from XK02 transaction it is editable. The UI properties can be contolled from "CL_BS_BP_GUIBB_BANK_ACCOUNT" class but we need to push the data that is entered in the screen to the bankend table BNKA. we are using the supplier type UI.

Any help is highly appreciated.
