• What is the cause and solution for SAP error message /SMB/CM_CONVERSION028 - Field of table and filed of value table have different domain ?

  The SAP error message /SMB/CM_CONVERSION028 indicates that there is a mismatch between the field in a table and the corresponding field in a value table due to different domains. This typically occurs in the context of data conversion or when trying to use a field that is expected to have a certain data type or domain, but the actual field does not match that expectation.
  Cause:
  
  Domain Mismatch: The field in the main table and the field in the value table are defined with different domains. A domain in SAP defines the technical attributes of a field, such as data type, length, and value range.
  Data Type Differences: The data types of the fields may not be compatible. For example, one field might be defined as a character type while the other is numeric.
  Configuration Issues: There may be configuration issues in the data model or in the way the tables are set up, leading to inconsistencies.
  
  Solution:
  
  Check Domain Definitions: Verify the domain definitions for both the field in the main table and the field in the value table. Ensure that they are consistent and compatible.
  
  Use transaction code SE11 (Data Dictionary) to check the domains.
  
  
  Adjust Field Definitions: If the domains are indeed different, you may need to adjust the field definitions in either the main table or the value table to ensure they match.
  Data Type Alignment: Ensure that the data types of the fields are compatible. If necessary, change the data type of one of the fields to match the other.
  Review Custom Code: If this error occurs in custom development, review the ABAP code to ensure that the fields are being used correctly and that there are no type mismatches in the code.
  Consult Documentation: If the issue is related to a specific SAP module or functionality, consult the relevant SAP documentation or support notes for guidance on how to resolve the issue.
