Reassigning funds center & causes budget inconsistencies; See long text

What causes this issue?

You have deactivated message control FICUSTOM151 supported by SAP for
hierarchy maintenance for fund centers in order to be able to reassign
funds centers with budget.
You now want to reassign funds center & to which budget values are
assigned. Note that, when fund centers with budget are reassigned,
budget inconsistencies may occur and as a result follow-on activities
are required.

How to fix this error?

You must execute the following activities after maintaining the funds
center hierarchy:
Program run <LS>Reconstruct Budget Values</>
Program run <LS>Reconstruct Assigned Values</>
You execute these programs in the menu of Funds Management, under
<LS>Budgeting -> Former Budgeting -> Tools -> Reconstruct -> Assigned
and/or Budget </>.
If you work with revenues increasing the budget, you must also start
program run <LS>Reconstruct Multiple Revenues</> using program
<DS:RE.BPDIST06>BPDIST06</>.
For more information on message control for the hierarchy maintenance of
fund centers, see the <DS:TX.LTCUSTOM151>long text on FICUSTOM151
