• What is the cause and solution for SAP error message ACM_SYNTAX194 - Rule won't apply to &1 because of redefinition in access control &2 ?

  The SAP error message ACM_SYNTAX194 indicates that there is a conflict in the access control rules defined in the system. Specifically, it means that a certain rule (identified by &1) cannot be applied because it has been redefined in another access control object (identified by &2). This typically occurs in the context of Access Control Management (ACM) within SAP GRC (Governance, Risk, and Compliance).
  Cause:
  
  Redefinition of Rules: The rule you are trying to apply has been redefined in another access control object. This can happen if multiple access control objects are trying to manage the same set of rules or if there are conflicting definitions.

  Configuration Errors: There may be errors in the configuration of the access control rules, leading to conflicts.
  
  Solution:
  
  Review Access Control Objects: Check the access control objects involved (&1 and &2) to understand how the rules are defined. Look for any conflicting definitions or redefinitions.
  Modify Rules: If you find that the rule has been redefined in a way that conflicts with your intended application, consider modifying the conflicting rule or the rule you are trying to apply.
  Check Hierarchical Relationships: If the rules are part of a hierarchy, ensure that the definitions at different levels do not conflict with each other.
  Consult Documentation: Refer to SAP documentation or guidelines on Access Control Management to ensure that the rules are set up correctly.
  Testing: After making changes, test the access control rules to ensure that they work as expected without conflicts.
