• What is the cause and solution for SAP error message AXT_MODEL186 - Application does not have a header table ?

  The SAP error message AXT_MODEL186, which states "Application does not have a header table," typically occurs in the context of SAP applications that require a header table for processing data. This error can arise in various scenarios, such as when working with custom applications, reports, or transactions that are expected to have a defined structure but do not.
  Cause:
  
  
  Missing Header Table Definition: The application or transaction you are trying to execute may not have a defined header table in its configuration. This can happen if the application was not properly set up or if there are missing components in the data model.
  
  
  Incorrect Configuration: The application might be incorrectly configured, leading to the system not recognizing the header table.
  
  
  Custom Development Issues: If the application is a custom development, there may be issues in the code where the header table is not being referenced or created correctly.
  
  
  Transport Issues: If the application was transported from one system to another (e.g., from development to production), there may have been issues during the transport that caused the header table to be omitted.
  
  
  Solution:
  
  
  Check Application Configuration: Review the configuration of the application to ensure that a header table is defined. This may involve checking the relevant customizing settings in the SAP system.
  
  
  Review Data Model: If you are working with a custom application, ensure that the data model includes a header table. You may need to define or adjust the data model in the relevant transaction (e.g., SE11 for Data Dictionary).
  
  
  Debugging: If you have access to the development environment, you can debug the application to identify where the header table is expected and why it is not being found.
  
  
  Consult Documentation: Check the documentation for the specific application or module you are working with to understand the expected structure and any prerequisites.
  
  
  Transport Check: If the issue arose after a transport, verify that all necessary objects were included in the transport request and that they were successfully imported into the target system.
  
  
  Contact SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance, especially if this is a standard application.
