• What is the cause and solution for SAP error message DB11185 - Compressed table: number of fields > 255! ?

  The SAP error message DB11185 indicates that you are trying to create or manipulate a compressed table that exceeds the limit of 255 fields. This is a limitation in the database structure for compressed tables in SAP, particularly when using certain database systems.
  Cause:
  The error occurs when:
  
  You have defined a table with more than 255 fields.
  You are attempting to compress a table that has more than 255 fields, which is not supported.
  
  Solution:
  To resolve this issue, you can consider the following approaches:
  
  
  Reduce the Number of Fields:
  
  Review the table structure and see if you can reduce the number of fields. This might involve:
  
  Merging fields that can logically be combined.
  Removing unnecessary fields that are not essential for your application.
  
  
  
  
  
  Split the Table:
  
  If reducing the number of fields is not feasible, consider splitting the table into multiple related tables. This can help you stay within the limit while maintaining the necessary data structure.
  
  
  
  Review Table Design:
  
  Reassess the design of your database schema. Sometimes, normalization can help reduce the number of fields in a single table by distributing data across multiple tables.
  
  
  
  Check for Unused Fields:
  
  Identify any fields that are not being used or are redundant. Removing these can help you stay within the limit.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation or your database documentation for any specific guidelines or best practices regarding table design and compression.
  
  
  
  Database-Specific Solutions:
  
  Depending on the database you are using (e.g., HANA, Oracle, etc.), there may be specific configurations or settings that can help manage large tables more effectively.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any updates or patches related to this error. Sometimes, SAP releases notes that provide additional guidance or fixes for known issues.
  Database Limitations: Familiarize yourself with the limitations of the database you are using in conjunction with SAP, as different databases may have different constraints.
  Performance Considerations: Keep in mind that while compressing tables can save space, it may also impact performance. Always test changes in a development environment before applying them to production.
  
  By following these steps, you should be able to address the DB11185 error and ensure your table design adheres to SAP's limitations.
