• What is the cause and solution for SAP error message DBOSC135 - Error while processing request; too many rows (&1) returned for structure ?

  The SAP error message DBOSC135 indicates that a database operation has returned too many rows for a specific structure, which exceeds the expected limit. This typically occurs in scenarios where a query or a data retrieval operation is expected to return a single row or a limited number of rows, but instead, it returns a larger dataset.
  Cause:
  
  Query Design: The SQL query or data retrieval logic may not be properly designed, leading to an unexpected number of rows being returned.
  Data Model Issues: There may be issues with the underlying data model, such as missing or incorrect relationships between tables, which can cause a query to return more rows than intended.
  Parameter Values: The parameters used in the query might not be restrictive enough, allowing too many records to be fetched.
  Configuration Issues: In some cases, the configuration of the data structure or the way the data is being processed may not align with the expected output.
  
  Solution:
  
  Review the Query: Check the SQL query or the data retrieval logic to ensure it is correctly formulated. Make sure that it includes appropriate filters to limit the number of returned rows.
  Check Data Relationships: Verify the relationships between the tables involved in the query. Ensure that joins are correctly defined and that they do not lead to a Cartesian product.
  Adjust Parameters: If the query uses parameters, ensure that they are set to values that will limit the result set appropriately.
  Limit the Result Set: If applicable, consider using SQL clauses like LIMIT or TOP to restrict the number of rows returned.
  Debugging: Use debugging tools or transaction codes (like SE11 for data dictionary, SE80 for object navigator) to analyze the data structure and the query execution plan.
  Consult Documentation: Refer to SAP documentation or community forums for specific guidance related to the transaction or report that is generating the error.
  
  Related Information:
  
  Transaction Codes: You may want to check the transaction codes involved in the process that led to this error. Common transaction codes for debugging include SE38 (ABAP Editor), SE11 (Data Dictionary), and ST22 (Dump Analysis).
  SAP Notes: Search for relevant SAP Notes in the SAP Support Portal that may address this specific error or provide patches and updates.
  Performance Considerations: If the query is expected to return a large dataset, consider optimizing the database performance or restructuring the data retrieval logic to handle larger datasets more efficiently.
  
  By following these steps, you should be able to identify the root cause of the DBOSC135 error and implement a solution to resolve it.
