Budget data is not shown in MR

Dear All,

I am working on setting Actual vs Budget PL in MR 2012. After I set up the budget model in AX 2009, I created column definition in MR, but I can't find "Budget" book code in "Book code/Attribute Category list", only "Actual" or "Actual Quantity" codes are avaialble in MR, so no budget data is shown up when I generate this AVB PL in MR.

I am not sure if i missed some set up in AX in MR?

Anybody could help me for this issue?

Thanks a lot,

Jim.
