• What is the cause and solution for SAP error message RS_ADSO_MODEL143 - Too many fields fields in index '&1': &2 (max = &3) ?

  The SAP error message RS_ADSO_MODEL143 indicates that there are too many fields in the index of an Advanced DataStore Object (ADSO). This error typically occurs when the number of fields in the index exceeds the maximum limit allowed by the system.
  Cause:
  The error is triggered when you attempt to create or modify an ADSO and the number of fields in the index exceeds the predefined maximum limit. This limit is set to ensure optimal performance and manageability of the data model. The specific limits can vary based on the version of SAP BW/4HANA or SAP BW on HANA you are using.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Reduce the Number of Fields in the Index:
  
  Review the fields that are currently included in the index of the ADSO. Determine if all fields are necessary for indexing.
  Remove any fields that are not essential for your reporting or querying needs.
  
  
  
  Use Composite Keys:
  
  If applicable, consider using composite keys instead of individual fields. This can help reduce the number of fields in the index.
  
  
  
  Re-evaluate the Data Model:
  
  Analyze the overall data model and see if the ADSO can be simplified or if certain fields can be moved to a different structure or table.
  
  
  
  Check for Redundant Fields:
  
  Look for any redundant fields that may be contributing to the index size. Consolidate or eliminate these fields where possible.
  
  
  
  Consult SAP Documentation:
  
  Refer to the official SAP documentation for your specific version to understand the maximum limits and best practices for designing ADSOs.
