• What is the cause and solution for SAP error message AXT_MODEL081 - Data type of key of &1 allows lower case ?

  The SAP error message AXT_MODEL081 indicates that there is an issue with the data type of a key field in your model. Specifically, it suggests that the key field is defined in a way that allows lower case characters, but the system is expecting an upper case format. This can occur in various contexts, such as when working with data models, database tables, or other structures where key fields are defined.
  Cause:
  
  Data Type Definition: The key field is defined with a data type that allows lower case characters (e.g., CHAR, VARCHAR) but is being used in a context that requires upper case (e.g., a key in a database table that is case-sensitive).
  Inconsistent Naming Conventions: The naming conventions used in your data model may not align with the expectations of the system, leading to this error.
  Data Model Configuration: The configuration of the data model may not be set up correctly, leading to conflicts in how keys are interpreted.
  
  Solution:
  
  Check Data Type Definition: Review the data type definition of the key field in your model. If it is set to allow lower case, consider changing it to a type that enforces upper case (if applicable).
  Adjust Naming Conventions: Ensure that all key fields are consistently defined using upper case letters. This may involve renaming fields or adjusting how they are referenced in your model.
  Modify Model Configuration: If the model configuration allows for case sensitivity, ensure that it is set to enforce upper case for key fields.
  Data Migration: If you are migrating data, ensure that the data being imported adheres to the expected case format for key fields.
  Consult Documentation: Refer to SAP documentation or guidelines for best practices regarding key field definitions and naming conventions.
