Creating a "plug" in DAX to bridge two data sets

[Natek]

We have a data warehouse that has transactional data (i.e. invoice, item number, etc). We also have our general ledger data in Oracle Hyperion which we recently migrated to our data warehouse.

The problem is, there are always slight differences in totals. For example, our transactional data set shows sales for the month as $14,166,718 vs our GL balance of $14,210,643. I would like to create a plug somehow so that if you are looking at the item and invoice detail, there will be a line that will list the $43,926 so that the total now agrees with the GL balance.

Does anyone have any idea how to accomplish this, or even know if it is possible?

Thanks

Nate
