• What is the cause and solution for SAP error message NGC_API_BASE028 - A value is already set for single value characteristic &1 ?

  The SAP error message NGC_API_BASE028 indicates that there is an attempt to set a value for a single-value characteristic that has already been assigned a value. This typically occurs in the context of SAP's Advanced Planning and Optimization (APO) or similar modules where characteristics are used to define product attributes.
  Cause:
  
  Duplicate Assignment: The error arises when a characteristic that is defined as a single-value characteristic is being assigned a value more than once in the same context (e.g., during a planning run or when creating a product).
  Incorrect Data Handling: The data being processed may have been incorrectly structured, leading to multiple assignments for the same characteristic.
  Configuration Issues: There may be issues in the configuration of the characteristics in the system, such as incorrect settings in the master data or planning data.
  
  Solution:
  
  Check Characteristic Assignment: Review the data being processed to ensure that the single-value characteristic is only being assigned once. If there are multiple assignments, you need to determine which one is correct and remove the others.
  Data Validation: Validate the input data to ensure that it adheres to the expected structure and does not contain duplicate entries for single-value characteristics.
  Review Configuration: Check the configuration of the characteristics in the system. Ensure that the characteristics are correctly defined as single-value and that there are no conflicting settings.
  Debugging: If you have access to debugging tools, you can trace the execution to see where the duplicate assignment is occurring and address it accordingly.
  Consult Documentation: Refer to SAP documentation or notes related to the specific module you are working with for any additional insights or known issues.
  
  Related Information:
  
  Single-Value Characteristics: These are characteristics that can only hold one value at a time. Examples include attributes like color, size, or any other attribute that should not have multiple values assigned simultaneously.
