Error while importing Leger Journals in Ax2012 using Excel Add-in

Hello All,

I am trying to Import Ledger Journals in Ax2012 R2 and using Excel Add-in. I am getting below error while importing Dimensions. Any suggestion would be appreciated .  

LedgerJournalTrans.createList Line=4, Pos=4, Xpath=/LedgerJournalTrans/LedgerJournalTrans[1] Method AxdBase.getDimensionId must be overridden.

LedgerJournalTrans.createList Line=4, Pos=4, Xpath=/LedgerJournalTrans/LedgerJournalTrans[1] Document Generic document could not be created. Error details: Method AxdBase.getDimensionId must be overridden.

Thanks,

Kumkum
