Hello,
Today we faced a new problem, the problem occurs when you need to do an Allocation Term and get duplicated values in general ledger. This occurs because you need the KB2986833, that corrects a bug in Table -> LedgerAllocations, when the system tries to make the right selection criteria.

Like this:
001

And then, you got this:
002

The KB can be found here: http://hotfixv4.microsoft.com/Microsoft%20Dynamics%20AX%202012%20R3/nosp/KB2986833/6.3.164.2732/free/477794_intl_i386_zip.exe.

The kb is included within CU8, this is for who are using just R3 without CU8.
