Understanding the CUKN Table
The CUKN table in SAP is primarily used to store customer-specific configuration information, especially within the SAP Variant Configuration (VC) module. It is closely related to product and material configurations.In tcode CU50 – Configuration Profile.
Key Uses:
- Storage of Configuration Characteristics: The table holds configuration characteristics and their corresponding values, which are associated with specific materials or product variants.
- Recording Customer-Specific Options: It records all customer-specific information related to material configurations, including selected options, settings, and variant parameters.
Table Structure:
- MANDT: Client
- KNUMA: Configuration Number, uniquely identifying the configuration
- VTYPE: Configuration Type, indicating the type of configuration (e.g., material configuration or production order configuration)
- OBJ_KEY: Object Key, typically related to the material or order associated with the configuration
- CHAR_VALUE: Configuration Characteristic Value, storing the specific value of the configuration characteristic
- CHAR_ID: Configuration Characteristic ID, identifying the configuration characteristic
In SAP Variant Configuration (VC), this table manages complex products with multiple configuration options. The system defines product variants through characteristic values such as color, size, and features. When creating materials or sales orders, the system retrieves customer configuration data from the CUKN table to perform material configuration and pricing operations.
The Issue: Missing Formulas with Line Breaks
After migrating data from SAP ECC to S/4 HANA, we observed that formulas containing carriage return and line feed characters in the CUKN table were not imported correctly. This resulted in missing formulas, which could potentially disrupt the configuration processes dependent on these formulas.
The Solution: Custom ABAP Tool
To address this issue, our SAP ABAP consultant team developed a custom tool designed to handle formulas with line breaks during the migration process. This tool effectively ensured that formulas containing carriage return and line feed characters were correctly imported into the CUKN table, preserving the integrity of the configuration data.
