How To Fix KQ449 - Assign cost component structure &1 to costing variant &3

KQ449 - Overview

• Message type: E = Error

• Message class: KQ - Error Messages for Customizing Product Costing

• Message number: 449

• Message text: Assign cost component structure &1 to costing variant &3

What causes this issue?

It is technically possible for two cost estimates with the same costing
type and the same valuation variant to overwrite each other when they
are saved.
It is therefore necessary to ensure that such cost estimates are saved
under the same memory structure (cost component layout).
Costing variant &V2& already has cost component structure &V1& assigned
to it. The currently entered costing variant &V3& has the same costing
type and valuation variant as costing variant &V2& entered earlier.
Therefore, cost component &V1& must be assigned to costing variant
&V3&.

How to fix this error?

Assign cost component structure &V1& to costing variant &V3&.
