How To Fix RS2HANA_CHECK089 - Length of filter string exceeds allowed limit

SAP Error Message - Details

• Message type: E = Error

• Message class: RS2HANA_CHECK - RS2HANA Check Report

• Message number: 089

• Message text: Length of filter string exceeds allowed limit

What causes this issue?

The generated filter string is &V1& characters longer than the maximum
length (&V2& characters) that is currently supported by the generated
stored procedure. If an attempt is made to access the generated view
with user &V3&, an error message will probably be displayed because the
filter string has to be shortened when it is retrieved by the stored
procedure.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message RS2HANA_CHECK089 - Length of filter string exceeds allowed limit ?

  The SAP error message RS2HANA_CHECK089 indicates that the length of a filter string exceeds the allowed limit when working with SAP HANA. This typically occurs in the context of data extraction or transformation processes, particularly when using SAP BW (Business Warehouse) or SAP BW/4HANA.
  Cause:
  The error is caused by the filter string used in a query or data extraction process exceeding the maximum length that SAP HANA can handle. This can happen when:
  
  A large number of values are being filtered in a single query.
  The filter string is constructed dynamically and inadvertently becomes too long.
  The use of complex conditions or multiple filters that concatenate to exceed the limit.
  
  Solution:
  To resolve this error, consider the following approaches:
  
  
  Reduce the Number of Filter Values:
  
  If possible, limit the number of values in the filter. Instead of filtering on a large set of values, consider breaking it down into smaller subsets or using ranges.
  
  
  
  Use Variables:
  
  Instead of hardcoding a long list of values, use variables in your queries. This can help manage the length of the filter string.
  
  
  
  Optimize the Query:
  
  Review the query logic to see if it can be simplified. Sometimes, complex conditions can be restructured to reduce the overall length of the filter string.
  
  
  
  Check for Unnecessary Filters:
  
  Ensure that all filters applied are necessary. Removing any redundant filters can help reduce the length.
  
  
  
  Batch Processing:
  
  If the data extraction is part of a batch process, consider breaking it into smaller batches that can be processed sequentially.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation for specific limits related to filter strings in your version of SAP HANA or BW. This can provide insights into the maximum allowed lengths and best practices.
  
  
  
  SAP Notes and Support:
  
  Check for any relevant SAP Notes that might address this specific error or provide additional guidance. If the issue persists, consider reaching out to SAP support for assistance.
  
  
  
  Related Information:
  
  SAP HANA Documentation: Review the official SAP HANA documentation for details on query limits and best practices.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they found effective.
  Performance Tuning: Consider performance tuning techniques for your queries to ensure they run efficiently without hitting length limits.
  
  By following these steps, you should be able to address the RS2HANA_CHECK089 error effectively.
