Distribution amount > plan amount (difference: &1) - please correct

What causes this issue?

The total of the depreciation distribution amounts is greater than the
comparison value.
Depending on the investment profile, this comparison value is either
the overall plan value or the budget value of the investment measures
(or is specified by a customer exit). The comparison value is not
allowed to be exceeded.

How to fix this error?

Reduce the amounts of the depreciation distribution or delete the
excessive entries.
