• What is the cause and solution for SAP error message USMD1564 - Model &1, entity type &2: Reuse of tables is not possible ?

  The SAP error message USMD1564 typically occurs in the context of SAP Master Data Governance (MDG) when there is an issue related to the reuse of tables in a data model. This error indicates that the system is unable to reuse certain tables for the specified model and entity type due to configuration or design constraints.
  Cause:
  
  Table Reuse Restrictions: The error often arises when the data model is designed in such a way that certain tables cannot be reused for the specified entity type. This could be due to the way the data model is structured or the relationships defined between entities.
  Inconsistent Configuration: There may be inconsistencies in the configuration of the data model, such as missing or incorrect definitions for the entity types or their associated tables.

  Review Data Model Configuration: Check the configuration of the data model in the SAP MDG system. Ensure that the entity types and their associated tables are correctly defined and that there are no conflicts.
  Check Table Relationships: Verify the relationships between the tables and entity types. Ensure that the tables intended for reuse are compatible with the entity type in question.
  Consult Documentation: Refer to the SAP documentation for Master Data Governance to understand the constraints and requirements for table reuse in your specific scenario.
