  Cause:
  
  Changes in Data Structure: The input structure for the report may have been altered due to changes in the database schema, such as adding or removing fields, or changing data types.
  Report Versioning: If the report was developed or modified in a different version of SAP or if there have been updates to the report itself, it may not be compatible with the current input structure.
  Transport Issues: If the report was transported from one system to another (e.g., from development to production), and the input structure was not consistent across systems, this error can occur.
  Custom Development: If the report is a custom development, changes made by developers without proper version control or documentation can lead to this issue.
  
  Solution:
  
  Check for Changes: Review any recent changes made to the database tables or structures that the report uses. This includes checking for any modifications in the data model or report logic.
  Update the Report: If the input structure has changed, the report may need to be updated to accommodate these changes. This could involve modifying the report's selection criteria, data retrieval logic, or output formatting.
  Re-transport the Report: If the report was transported, ensure that all necessary objects and dependencies were included in the transport request. You may need to re-transport the report after ensuring that the input structure is consistent across systems.
  Consult Documentation: Check any documentation related to the report for notes on changes to the input structure. This can provide insights into what modifications may be necessary.
  Test in Development: If possible, test the report in a development or quality assurance environment after making changes to ensure that it runs correctly before deploying to production.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific report or transaction code you are working with.
  Transaction Codes: Use transaction codes like SE80 (Object Navigator) or SE38 (ABAP Editor) to analyze the report and its dependencies.
  Debugging: If you have access to debugging tools, you can run the report in debug mode to identify where the input structure is failing.
  Collaboration: Work with your SAP Basis or ABAP development team to resolve the issue, especially if it involves changes to the underlying data structures.
