• What is the cause and solution for SAP error message RSDRI_HDB029 - Conversion for object &1 not supported ?

  The SAP error message RSDRI_HDB029: Conversion for object &1 not supported typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the conversion of data types or structures during data extraction or reporting, particularly when using HANA as the database.
  Cause:
  
  
  Data Type Mismatch: The error often arises when there is a mismatch between the data types defined in the BW model and those in the underlying HANA database. For example, if a field in BW is defined as a certain data type (like CHAR or NUMC) but the corresponding field in HANA is of a different type (like VARCHAR or INTEGER), the conversion may fail.
  
  
  Unsupported Data Types: Some data types or structures in BW may not have a direct equivalent in HANA, leading to conversion issues.
  
  
  Modeling Issues: If the InfoObject or InfoProvider is not correctly modeled or if there are inconsistencies in the data model, it can lead to this error.
  
  
  Data Source Issues: If the data source is not properly configured or if there are issues with the data extraction process, it can also trigger this error.
  
  
  Solution:
  
  
  Check Data Types: Review the data types of the InfoObjects in BW and ensure they match the corresponding fields in the HANA database. Adjust the data types in BW or HANA as necessary.
  
  
  Update InfoObjects: If there are changes in the underlying data model, ensure that the InfoObjects are updated accordingly. This may involve re-defining the InfoObjects or adjusting the data source.
  
  
  Re-activate Objects: Sometimes, simply re-activating the InfoObjects or InfoProviders can resolve the issue. This can be done in the SAP BW modeling tools.
  
  
  Check Data Source Configuration: Ensure that the data source is correctly configured and that there are no issues with the extraction process. This includes checking for any transformations that may be causing the issue.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error. There may be patches or updates available that resolve known issues.
  
  
  Debugging: If the issue persists, consider debugging the data flow to identify where the conversion is failing. This may involve looking at the data extraction process, transformations, and the data loading process.
