How To Fix KA387 - Amount in calculation base & exceeds maximum value

KA387 - Overview

• Message type: E = Error

• Message class: KA - CO Overhead Costs: Overhead, Accrual Calculation

• Message number: 387

• Message text: Amount in calculation base & exceeds maximum value

What causes this issue?

For a base line in the costing sheet, the system has calculated an
amount for calculation base &V1& which has more than 11 digits.
However, only amounts with a maximum of 11 digits can be processed for
each base line, such as $999,999,999.99 USD or 99,999,999,999 lire.

System Response

The overhead is not applied.

How to fix this error?

Subdivide the cost element intervals in the calculation bases so that
the amounts calculated remain under this limit.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

Example:
The following amounts are posted to the objects for which overhead is
to be calculated:
Cost element Amount
400000 999,999,999.99 USD
400010 999,999,999.99 USD
WRONG procedure:
You have defined the following calculation base:
Calculation base B000:
From CE To CE
400000 400010
You use the following costing sheet:
Costing sheet: A00000
Line Base Overhead Name From To line CR
10 B000 Material 0 0
20 C000 OH material 10 0 E01
CORRECT procedure:
Define the following calculation bases:
Calculation base X001:
From CE To CE
400000 400000
Calculation base X002:
From CE To CE
400010 400010
Define the following costing sheet:
Costing sheet: Y00001
Line Base Overhead Name From To line CR
10 X001 Material 1 0 0
15 X002 Material 2 0 0
20 C000 OH material 10 15 E01
