• What is the cause and solution for SAP error message AXT_MODEL147 - DTEL &1 and key field of check table &2 have different domains('&3'/'&4') ?

  The SAP error message AXT_MODEL147 indicates a mismatch between the domains of a data element and a key field in a check table. This typically occurs when you are trying to create or modify a data model, and the data types or domains of the fields involved do not match.
  Cause:
  
  Domain Mismatch: The error arises when the data element (DTEL) and the key field of the check table have different domains. This means that the data types or the characteristics defined in the domains are not compatible.
  Inconsistent Data Types: The fields may have been defined with different lengths, types (e.g., CHAR vs. NUMC), or other attributes that prevent them from being used together.
  Modeling Errors: This can also occur due to errors in the data model configuration, where the relationships between fields are not correctly defined.
  
  Solution:
  
  Check Domain Definitions: Review the domain definitions for both the data element and the key field in the check table. Ensure that they are compatible in terms of data type, length, and other attributes.
  Modify Domains: If necessary, modify one of the domains to ensure they match. This may involve changing the data type or length of one of the fields.
  Adjust Data Model: If the mismatch is due to a modeling error, adjust the data model to ensure that the fields are correctly defined and related.
  Recreate Data Element: If the data element is incorrectly defined, consider recreating it with the correct domain that matches the check table key field.
  Consult Documentation: Refer to SAP documentation or consult with a technical expert to understand the implications of changing domain definitions, as it may affect other areas of the system.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like SE11 (Data Dictionary) to check and modify domain definitions.
  Data Element and Domain: Understand the difference between data elements and domains in SAP. A domain defines the technical attributes of a field, while a data element defines the semantic meaning and can reference a domain.
  Testing: After making changes, ensure to test the data model to confirm that the error is resolved and that the system behaves as expected.
  Transport Requests: If changes are made in a development environment, ensure that they are properly transported to the quality and production environments.
  
  By following these steps, you should be able to resolve the AXT_MODEL147 error and ensure that your data model is correctly configured.
