• What is the cause and solution for SAP error message /AIF/MES116 - Recursive multi-level mapping (&1 -> &2); check structure mapping ?

  The SAP error message /AIF/MES116 Recursive multi-level mapping (&1 -> &2); check structure mapping typically occurs in the context of the Application Interface Framework (AIF) when there is an issue with the mapping configuration of structures in your AIF setup. This error indicates that there is a recursive mapping issue where the system is trying to map a structure to itself or there is a circular reference in the mapping definitions.
  Cause:
  
  Recursive Mapping: The error suggests that the mapping configuration is set up in such a way that it leads to a recursive call. This can happen if a structure is mapped to itself directly or indirectly through other mappings.
  Circular References: If there are multiple mappings that reference each other in a circular manner, it can lead to this error.
  Incorrect Mapping Configuration: The mapping definitions may not be correctly set up, leading to confusion in how the data should be transformed.
  
  Solution:
  
  Review Mapping Definitions: Check the mapping definitions in the AIF configuration. Look for any mappings that might be referencing themselves or creating a circular reference.
  Adjust Structure Mapping: If you find a recursive mapping, adjust the structure mapping to eliminate the recursion. Ensure that each mapping points to a different structure or that the mapping logic is linear.
  Test Mappings: After making changes, test the mappings to ensure that the error does not occur again. Use the AIF monitoring tools to validate the mappings.
  Consult Documentation: Refer to SAP documentation or guides related to AIF mapping to ensure that you are following best practices for structure mapping.
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance, providing them with details of your mapping configuration.
  
  Related Information:
  
  AIF Documentation: SAP provides extensive documentation on the Application Interface Framework, which includes guidelines on mapping and configuration.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /AIF/IFMON for monitoring interfaces and /AIF/IFCONFIG for configuration.
  Community Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, and solutions shared.
  
  By carefully reviewing your mapping configurations and ensuring that there are no recursive or circular references, you should be able to resolve the error message /AIF/MES116.
