How To Fix CU393 - Error in reference characteristic &1 due to cause &2 (-> see long text)

SAP Error Message - Details

• Message type: E = Error

• Message class: CU - Variants / configuration messages

• Message number: 393

• Message text: Error in reference characteristic &1 due to cause &2 (-> see long text)

What causes this issue?

An incorrect or wrongly-used object characteristic has been located in
the knowledge base.
Causes:
1: Character for variant conditions cannot have multiple values.
2: A different characteristic already exists with a reference to the
same table field.
3: The characteristic was not used by the modeller in classes or object
dependencies. The characteristic is however required for processing in
SCE (for example, condition characteristic for deriving 1:1 variant
conditions).

System Response

For:
1: In the SCE knowledge base, the characteristic is treated as a
characteristic with multiple values.
2: The generation of the knowledge base was cancelled.
3: The characteristic was automatically copied by the knowledge base
generation.

How to fix this error?

For
1: Define the characteristic for variant conditions as a characteristic
with multiple values.
2: Ensure that one object characteristic is avaiable for each reference
field (table field) in the knowledge base.
