CKMLLA007 - Overview

• Message type: E = Error

• Message class: CKMLLA - Message for Activity Update in Quantity Structure

• Message number: 007

• Message text: The selection is not unique, please enter a plant.

What causes this issue?

Activities/business processes are assigned to a controlling area, but
the company code and valuation are still relevant for valuation. In
cross-company code cost accounting, it is possible that an activity or
a business process is used in the material ledger in different plants
with different currency and valuation settings. Therefore when creating
master data, the activity update in the actual quantity structure is
differentiated not just by activity type/business process, but also the
plant is considered

System Response

If the system does not recognize the plant, it reads all plants in
which the particular activity type/business process was used in that
period. If the system only finds one plant meeting that criteria, that
plant is used. Otherwise, you will have to specify a plant.

How to fix this error?

Enter a plant whose currency/valuation settings correspond to what you
need at the moment.

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