  The SAP error message USMD7022, which states "Change of model &1: Cannot determine effect on rules," typically occurs in the context of SAP Master Data Governance (MDG) when there is an issue with the rules associated with a change in a data model. This error indicates that the system is unable to determine how a change in the specified model (denoted by &1) affects the existing rules that govern the data.
  Causes:
  
  Inconsistent Data Model: Changes made to the data model may not be properly reflected in the associated rules, leading to inconsistencies.
  Missing or Incorrect Rule Definitions: The rules that are supposed to govern the data model may be missing, incorrectly defined, or not properly linked to the model.

  Check Rule Activation: Ensure that all relevant rules are activated and properly linked to the data model. Sometimes, rules may need to be reactivated after changes are made.
  Use the MDG Change Request: If applicable, use the MDG change request process to manage changes to the data model and rules systematically.
