In Dynamics 365 for Operations (AX), Business requires the separate reporting on financial dimension (Business Units) within the same legal entity. Therefore, business will use interunit accounting functionality along with bridging accounting. The interunit accounting functionality should enable in the background when interunit transaction triggers.
When user want to select bridged transactions, he will get the interunit transaction as well.
With the code changes in this hotfix, user will be able to select only Bridged transaction in General Journal.
