• Message number: 296

• Message text: &1 &2: Single determ. from object table is not possible for cluster data

What causes this issue?

The relationship data for &V1& &V2& is meant to uploaded from the

cluster table, you can copy this table into a transparent object table
using transaction CNV_10020_COPY.

Cluster tables can contain multiple records for a single key, making it impossible for the system to determine a single record based on the provided key. This situation often occurs when:
  
  Data Structure: The data being processed is stored in a cluster table, and the migration tool is trying to access it as if it were a transparent table.
  Key Uniqueness: The key used to access the data does not uniquely identify a
