DMF import of Ledger Trans problem using Excel add-in

Hello all!!

I am currently trying to import data into AX 2012 using DMF. I reffered to the following link…/dynamics-ax-2012-ledger.html to import Ledger Trans…but i do not have any other data sources other than HCMPositionList.

In the before mentioned blog, general ledger data source is present in the “Add Data” form. but i have nothing.

Thanks in advance!!
