  The SAP error message USMD2_MAC006 indicates a mismatch in the expected data structure during a data migration or data transfer process, particularly in the context of SAP Master Data Governance (MDG). The message states that a specific element (denoted as &1) was expected, but a different element (denoted as &2) was provided instead.
  Cause:
  This error typically arises due to one of the following reasons:
  
  Data Structure Mismatch: The data being processed does not conform to the expected structure defined in the MDG configuration. This could happen if the data source has been modified or if there are discrepancies in the data mapping.
  Incorrect Mapping: The mapping between the source and target data structures may be incorrect, leading to the wrong element being specified.
  Versioning Issues: If there are different versions of the data model or if the data model has been changed without updating the relevant mappings, this error can occur.
  Configuration Errors: There may be issues in the configuration of the MDG process, such as incorrect settings in the data model or the process flow.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Data Mapping: Review the data mapping configuration to ensure that the source and target elements are correctly aligned. Make sure that the expected element (as indicated by &1) is being provided in the data.
  
  
  Validate Data Structure: Ensure that the data being imported or processed adheres to the expected structure. You may need to validate the data against the data model defined in MDG.
