How To Fix CK428 - Overflow while evaluating operation & in routing &

SAP Error Message - Details

• Message type: E = Error

• Message class: CK - Product Costing Messages

• Message number: 428

• Message text: Overflow while evaluating operation & in routing &

What causes this issue?

In routing &V2&, you entered the standard value &V3& for activity type
&V4& in operation &V1&.
Using the formulas in the work center and the standard values in the
operation, the system computes how much activity is expected per
activity type. This activity is valuated using the activity prices in
Cost Center Accounting to calculate the planned costs for the
operation.
In the case at hand, the standard value results in a value that is too
large for the system to handle.

System Response

The system cannot calculate the planned costs for operation &V1&.

How to fix this error?

Check the standard value &V3& for activity type &V4& in the master data
for routing &V2&.
