Incorrect calculation in the Cost Component split in 12 Currency Type

Dear colleagues,
We person 1 contented with Material Ledger wherever we request your support. There is an incorrect calculation successful the Cost Component divided successful 12 Currency Type successful our system.
The main contented is that the Cost Component divided successful ‘12’ Currency Type is not adjacent to ‘10’ Currency Type. To beryllium clear, successful our solution we activated ‘12’ Currency Type conscionable successful case. We don’t usage Profit Center Accounting and according to Blueprint, the sums successful ‘12’ Currency Type has to beryllium adjacent to ‘10’ Currency Type. 
We investigated that lawsuit by ourselves and recovered retired that the quality were calculated owed to PP-order Settlement.

Actually aft investigation we tin corroborate that determination are nary reasons the sums successful Cost Component splitting successful ‘10’ and ‘12’ Currency Types to beryllium not equal. But we spot the other concern successful the system.
