  Other master data records.
  Transactions or documents that utilize the master data.
  Relationships or dependencies that have not been resolved.
  
  
  
  Data Integrity Constraints: SAP enforces data integrity rules to ensure that changes do not lead to inconsistencies in the database. If a record is linked to other records, the system prevents changes to maintain data integrity.

  To resolve the USMDZ3045 error, you can take the following steps:
  
  
  Identify References: Use transaction codes or reports to identify where the references to the master data record exist. This may involve:
