Financial dimensions - import ledger journal from csv file

Hello,
if someone was possible to retrieve your account details and dimensions from string. I have this problem: getting into a csv file transactions where the account is given in the form of mainaccount-value dimension-value dimension-value dimension (string example 402020-KUP-SWA-51000). I can't identify what dimension is first value, second value and third value. To save this in AX2012 I need to know both size and value. I'll be grateful for the X ++ code.
