  The SAP error message USMD1618 indicates that there is an issue with the data model and entity type in the context of SAP Master Data Governance (MDG). Specifically, it states that "Reuse active areas are not supported," which typically means that the system is encountering a problem with the configuration of active areas in the data model.
  Cause:
  
  Active Area Configuration: The error usually arises when there is an attempt to use a reuse active area in a context where it is not supported. Reuse active areas are typically used to share data across different entities or models, but certain configurations or entity types may not allow for this.
  Entity Type Restrictions: Some entity types may have restrictions on how they can interact with active areas, leading to this error when trying to use them inappropriately.
  Data Model Issues: There may be inconsistencies or misconfigurations in the data model that prevent the reuse of active areas.
  
  Solution:
  
  Check Data Model Configuration: Review the configuration of the data model and ensure that the active areas are set up correctly. Make sure that the entity types involved are compatible with the reuse active areas.
  Adjust Entity Types: If the entity type is not supposed to use a reuse active area, consider modifying the data model to remove the reuse active area from that entity type.
  Consult Documentation: Refer to SAP documentation for Master Data Governance to understand the limitations and requirements for using reuse active areas with specific entity types.
  Testing: After making changes, test the data model to ensure that the error is resolved and that the data can be processed as expected.
