SAP S/4HANA Error 708: Duplicate Column Keycopy
Description
This error occurs when an attempt is made to create or add a column named 'keycopy' to an existing database table that already contains a column with that name. It typically arises during data migration, custom development deployments, or schema modification processes within SAP S/4HANA.
Error Message
ERR_SQL_EXST_COLUMN_KEYCOPY: Column keycopy already exists
Known Causes
4 known causesManual Schema Modification
An administrator or developer manually tried to add a column named 'keycopy' to a table using direct SQL commands or database tools, but the column already exists.
Data Migration Script Conflict
A data migration script or program attempts to create a 'keycopy' column in a target table that already has a column with the same name, indicating an issue with the script logic or target environment setup.
Custom Development Deployment
A custom SAP development, extension, or add-on containing schema changes tries to define or create a 'keycopy' column in a standard or custom table where it is already present, leading to a conflict.
Incomplete Prior Update
A previous system update, patch, or schema change operation failed or was interrupted, leaving the database in a state where a subsequent attempt to add 'keycopy' detects its pre-existence incorrectly.
