SAP Classes (tables KLAH, KSSK, KLAT, KSML) and SAP Characteristics (tables INOB, AUSP, CABN, CABNT, CAWN, CAWNT) are master data typically associated with materials and batches.

This data uses internal numbers that can be specific to each system. Gold Client copies data at the table record level so numbering used in the source system will be imported into the target system. If manually created classes and characteristics exist in the target using different internal numbers than the source, data corruption could occur due to a misalignment of these internal numbers.
Figure 2 - Example of Characteristics created in DEV and moved to QA and PROD system using ALE
In this scenario, while copying characteristics via Gold Client it will overwrite the entries based on the key fields and potentially corrupt data due to duplicated/missing characteristics.

Strategies to consider in order of preference to avoid this issue:
Only copy classes and characteristics with Client Construct process in Gold Client. This full table copy process can remove all existing classes and characteristics records in the target before importing source data. The Delete Table Data Before Import needs to be selected during the Client Construct -> Client Importer process.
Any classes and characteristics data manually created or moved with ALE in the target would be deleted with this process.

Adjust Gold Client Data Echo configuration to exclude classes and characteristics data. Consider marking the following linkages inactive in the Data Echo configuration
CA - EQUIPMENT DATA -> LINK - OBJECT TO CLASSIFICATION
MM - BATCHES (MCH1) -> CA - CHARACTERISTICS
MM - BATCHES (MCHA) -> CA - CHARACTERISTICS
MM - CONFIGURABLE MATERIAL -> LINK - MATERIAL TO CLASS
MM - CONFIGURABLE MATERIAL -> LINK - MATERIAL TO CLASS
MM - MATERIAL MASTER W/ VC DATA -> MM - CONFIGURABLE MATERIAL
