• What is the cause and solution for SAP error message DB877 - Logical database & called nested ?

  The SAP error message DB877 typically indicates an issue related to logical databases and nested calls in the context of database access within an ABAP program. This error can occur when there is an attempt to call a logical database that is already being processed or when there are issues with the structure of the logical database calls.
  Cause:
  
  Nested Calls: The error often arises when a logical database is called within another logical database or when a logical database is called recursively. SAP does not allow nested calls to logical databases.
  Incorrect Program Logic: The program logic may inadvertently lead to a situation where a logical database is invoked multiple times in a nested manner.
  Configuration Issues: There may be issues with the configuration of the logical database itself, such as incorrect definitions or relationships.
  
  Solution:
  
  Review Program Logic: Check the ABAP program for any nested calls to logical databases. Ensure that logical databases are not being called within other logical database calls.
  Refactor Code: If nested calls are necessary for your logic, consider refactoring the code to avoid using logical databases in a nested manner. You may need to retrieve data using standard SELECT statements instead.
  Check Logical Database Configuration: Verify the configuration of the logical database in transaction SE37 (Function Builder) or SE11 (Data Dictionary). Ensure that the logical database is defined correctly and does not have any recursive calls.
  Debugging: Use the ABAP debugger to trace the execution of the program and identify where the nested call is occurring. This can help pinpoint the exact location in the code that is causing the issue.
  
  Related Information:
