• What is the cause and solution for SAP error message GT814 - Overflow when calculating a temporary name for table & ?

  The SAP error message GT814, which indicates an "Overflow when calculating a temporary name for table &," typically occurs during the generation of temporary table names in ABAP programs. This error is often related to the internal handling of temporary tables, particularly when the system runs out of available identifiers or when there is a naming conflict.
  Causes:
  
  Excessive Temporary Tables: The program may be creating too many temporary tables, leading to an overflow in the naming convention used by SAP.
  Long Running Processes: If a process runs for an extended period and creates temporary tables dynamically, it may exhaust the available naming space.
  Naming Conflicts: If there are naming conflicts or if the naming convention exceeds the allowed limits, it can lead to this error.
  System Limitations: The underlying database or SAP system may have limitations on the number of temporary objects that can be created.
  
  Solutions:
  
  Optimize Temporary Table Usage: Review the ABAP code to minimize the creation of temporary tables. Use internal tables or other data structures where possible.
  Clean Up Temporary Tables: Ensure that temporary tables are being properly deleted or cleaned up after their use to free up naming space.
  Refactor Code: If the code is generating temporary tables in loops or recursive calls, consider refactoring it to reduce the number of temporary tables created.
  Check for Naming Conflicts: Ensure that the naming conventions used for temporary tables do not conflict with existing names or exceed the character limits.
  Increase System Resources: If applicable, consider increasing the resources allocated to the SAP system or database to handle more temporary objects.
