Doug is right. Manual Proration has not changed in 92B.

If the currency of the Misc Charge Vendor is not the same as the currency for the Item Vendor, the allocation will need to be made in the Item Vendor's currency.

For example: If the Item is in Source Currency CAD and the Misc Charge is in Home currency USD. The amount entered in the 'Allocated Misc.' needs to be in CAD.

I suggest that you add 'Alloc Costs - Home' to the column editor. The 'Alloc Costs - Home' for all of the item allocations must add up to the amount for the Misc Charge.
