• What is the cause and solution for SAP error message AXT_MODEL080 - Data type of key &1 does not allow lower case ?

  The SAP error message AXT_MODEL080 indicates that there is an issue with the data type of a key field in your model. Specifically, it states that the data type does not allow lower case characters. This error typically arises in scenarios involving data modeling, such as when working with SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The primary cause of this error is that the key field in question is defined with a data type that is case-sensitive and does not permit lower case letters. This can happen if:
  
  The key field is defined as a character type (CHAR) with a specific length that does not support lower case.
  The data being input or processed contains lower case letters, which are not allowed for that specific key field.
  
  Solution:
  To resolve the AXT_MODEL080 error, you can take the following steps:
  
  
  Check Data Type Definition:
  
  Review the data type definition of the key field in your model. Ensure that it is set to a type that allows for the intended character set (e.g., upper case only).
  
  
  
  Modify Input Data:
  
  If the input data contains lower case letters, you will need to convert it to upper case before processing. This can be done using string manipulation functions in your ETL (Extract, Transform, Load) process or in the data source.
  
  
  
  Adjust Model Configuration:
  
  If possible, consider changing the model configuration to allow for a more flexible data type that can accommodate lower case letters, if that aligns with your business requirements.
  
  
  
  Data Validation:
  
  Implement data validation checks to ensure that any data being loaded into the model adheres to the required format and case sensitivity.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidelines on data types and their constraints within your version of SAP.
