• What is the cause and solution for SAP error message DB875 - Logical database & does not support multiple calls ?

  The SAP error message DB875 typically indicates that there is an issue with the logical database being used in a report or program. The message states that the logical database does not support multiple calls, which means that the logical database is not designed to handle multiple accesses or calls in a single execution context.
  Cause:
  
  Multiple Calls to Logical Database: The logical database is being called multiple times within the same program or report execution. This can happen if the program is structured in a way that it tries to access the logical database more than once.
  Incorrect Program Logic: The program may have loops or conditions that inadvertently lead to multiple calls to the logical database.
  Use of Subroutines or Function Modules: If the logical database is called within a subroutine or function module that is invoked multiple times, it can lead to this error.
  
  Solution:
  
  
  Review Program Logic: Check the program or report logic to ensure that the logical database is only called once. If you need to access data multiple times, consider storing the results in an internal table after the first call and then using that table for subsequent operations.
  
  
  Use of Internal Tables: Instead of calling the logical database multiple times, fetch the data once and store it in an internal table. You can then process this internal table as needed without making additional calls to the logical database.
  
  
  Refactor Code: If the logical database is being called within loops or multiple function calls, refactor the code to ensure that the call is made only once.
  
  
  Check for Nested Calls: Ensure that there are no nested calls to the logical database from within other logical databases or function modules.
  
  
  Related Information:
  
  Logical Databases: In SAP, logical databases are used to provide a structured way to access data from the database. They are designed to encapsulate the data retrieval logic and provide a consistent interface for reports.
  Performance Considerations: Calling a logical database multiple times can lead to performance issues, as each call may involve database access and data retrieval.
  Debugging: Use the debugger to trace the execution of the program and identify where the multiple calls to the logical database are occurring.
  
  By following these steps, you should be able to resolve the DB875 error and ensure that your program runs smoothly without attempting to make multiple calls to the logical database.
