I have two questions,(1).In dme payment, any t-code or program can toggle DME payment media or house bank, for example, payment method C, i want to change from house bank 1 to house bank 2, I want to change payment method C from citibank dme tree D1 to HSBC dme tree D2?
(2) if my house bank is citibank, can i use DME tree D2( HSBC DME tree structure), then do citibank accept D2 format? money is deducted from house bank citibank?, is DME tree setup based on country level?
