electronic bank statement 2

Hi,

in Spro i have this :

- account symbol <b>XXX</b> assigned to account <b>XXXXX</b>X

- posting rule <b>MCHE</b> : <b>40</b> XXX <b>50</b> Bank (ST)

- external transaction <b>01</b> assigned to posting rule <b>MCHE</b>

but when i receive electronic bank statement from the bank (that contain <b>01</b> as an external transaction ) and i integrate it with FF_5 i have a document posted with account <b>YYYYYY</b> (and not account <b>XXXXXX</b> that determined in the above implementation).why it isn't posted with account <b>XXXXXX</b>? and how to do?

so their experts i hope your help to solve that.

regards
