• What is the cause and solution for SAP error message AXT_MODEL084 - Data type of &1 (&2) does not match ?

  The SAP error message AXT_MODEL084 indicates that there is a data type mismatch in the context of a model or data structure. Specifically, it suggests that the data type of a field or variable does not match the expected data type defined in the model or structure.
  Cause:
  
  Data Type Mismatch: The most common cause of this error is that the data type of a field in the source data does not match the data type defined in the target structure or model. For example, if a field is defined as an integer in the model but the incoming data is a string, this error will occur.
  Incorrect Mapping: If you are using a mapping tool or process, the mapping between source and target fields may be incorrectly defined, leading to mismatched data types.
  Changes in Data Structure: If there have been recent changes to the data structure or model definitions, and the data being processed has not been updated accordingly, this can lead to mismatches.
  
  Solution:
  
  Check Data Types: Review the data types of the fields in both the source data and the target model. Ensure that they match. You can do this by checking the data dictionary (SE11) or the relevant data model definitions.
  Adjust Mapping: If you are using a mapping tool, verify that the mappings are correctly defined and that the data types align. Adjust the mappings as necessary to ensure compatibility.
  Data Transformation: If the source data cannot be changed, consider implementing a transformation step to convert the data into the expected format before it reaches the model.
  Update Model Definitions: If the source data is correct and the model is outdated, consider updating the model definitions to accommodate the new data types.
  Testing: After making changes, perform thorough testing to ensure that the error is resolved and that the data is processed correctly.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), or SE37 (Function Module) to investigate the data types and structures involved.
  Debugging: If the error persists, consider using the debugger to trace the data flow and identify where the mismatch occurs.
  Documentation: Review any relevant documentation or change logs that might indicate recent changes to data structures or models that could have led to this issue.
  
  By following these steps, you should be able to identify the cause of the AXT_MODEL084 error and implement a solution to resolve it.
