• What is the cause and solution for SAP error message USMD_CMM030 - Model type &1 has &2 key components for entity type &3 but &4 were passed ?

  The SAP error message USMD_CMM030 typically occurs in the context of SAP Master Data Governance (MDG) when there is a mismatch between the expected key components for a specific model type and the actual key components that were passed during a data operation (such as creating or updating master data).
  Cause:
  The error message indicates that the model type specified (represented by &1) has a defined number of key components (represented by &2) for a particular entity type (represented by &3), but the number of key components that were actually passed in the operation (represented by &4) does not match the expected number. This discrepancy can occur due to:

  Configuration Issues: The model configuration in SAP MDG may not be aligned with the data being processed, leading to mismatches in expected key components.
