  The SAP error message SB251, which states "Internal error: Structure &1 does not exist," typically indicates that the system is trying to access a structure that is not defined or has not been properly activated in the SAP system. This can occur in various contexts, such as during the execution of a program, report, or transaction that relies on specific data structures.
  Causes:
  
  Missing Structure: The structure referenced in the error message does not exist in the system. This could be due to a missing transport or an incomplete installation of a component.
  Inactive Structure: The structure may exist but is not activated. This can happen if the structure was recently created or modified and has not been activated in the system.
  Transport Issues: If the structure was part of a transport request that was not successfully imported, it may not be available in the target system.

  Transport Request:
