• What is the cause and solution for SAP error message FDT_HANA303 - Row &1 column &2: Only single value enumerations are allowed ?

  The SAP error message FDT_HANA303 indicates that there is an issue with the data model or the data being processed in SAP HANA, specifically related to the use of enumerations. The message states: "Row &1 column &2: Only single value enumerations are allowed." This typically occurs when a data field is expected to have a single value enumeration but is instead receiving multiple values or an invalid format.
  Cause:
  
  
  Multiple Values in a Single-Value Field: The error often arises when a field that is defined to accept only a single value is being populated with multiple values. This can happen due to incorrect data input or data transformation processes that do not adhere to the expected format.
  
  
  Data Model Definition: The data model may be incorrectly defined, allowing for multiple values where only a single value is expected. This could be due to misconfiguration in the data model or incorrect mapping of fields.
  
  
  Data Source Issues: If the data is being pulled from an external source, the source data may not conform to the expected structure, leading to this error.
  
  
  Solution:
  
  
  Check Data Input: Review the data being input into the system. Ensure that the fields in question are populated with single values only. If multiple values are being provided, modify the input to conform to the expected single value format.
  
  
  Review Data Model: Examine the data model definition in SAP HANA. Ensure that the fields are correctly defined to accept the appropriate data types and formats. If necessary, adjust the model to accommodate the data correctly.
  
  
  Data Transformation Logic: If the data is being transformed or processed before being loaded into HANA, review the transformation logic. Ensure that it correctly handles the data and does not inadvertently create multiple values for fields that should only have a single value.
  
  
  Debugging: Use debugging tools to trace the data flow and identify where the multiple values are being introduced. This can help pinpoint the exact location in the process where the error is occurring.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for additional insights or similar cases. There may be specific guidelines or best practices for handling enumerations in your version of SAP HANA.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context on handling enumerations in HANA.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Training and Resources: Consider additional training or resources on data modeling in SAP HANA to better understand how to define and manage enumerations effectively.
  
  By following these steps, you should be able to identify the root cause of the FDT_HANA303 error and implement a solution to resolve it.
