This error typically occurs in the context of SAP's Flexible Real Estate Management (RE-FX) or similar modules where data structures are defined.
  Cause:
  The error is caused by exceeding the limit of fields that can be defined in a sub-table. In SAP, there are certain limitations on the number of fields that can be included in a table structure, and when this limit is exceeded, the system generates this error message.
  Solution:
  To resolve this issue, you can consider the following approaches:
  
  
  Review Table Structure: Analyze the structure of the sub-table that is causing the error. Check if all fields are necessary and if any can be removed or consolidated.
  
  
  Field Consolidation: If possible, consolidate fields that serve similar purposes. For example, if you have multiple fields for different types of data that could be combined into a single field, do so.
  
  
  Use of Additional Tables: If the sub-table is too large, consider breaking it down into multiple related tables. This can help distribute the fields across different tables and avoid hitting the limit.
  
  
  Custom Development: If the standard functionality does not meet your needs, consider custom development. You may need to create a custom data structure that can accommodate more fields, but this should be done with caution and in accordance with SAP best practices.
  
  
  Consult SAP Documentation: Check the SAP Help Portal or relevant documentation for any updates or guidelines regarding the limitations of table fields in your specific version of SAP.
  
  
  SAP Support: If the issue persists and you cannot find a suitable solution, consider reaching out to SAP Support for assistance. They may provide insights or patches that can help resolve the issue.

  Testing: After making changes to the table structure, ensure thorough testing to confirm that the changes do not adversely affect existing functionality.
  
  By following these steps, you should be able to address the error and optimize your table structure in SAP.
