NAA331 - Details

• The SAP error message NAA331 indicates that there is a conflict between the settlement schema and the price determination schema in the configuration of your SAP system. Specifically, it means that the settlement schema you are trying to use is the same as the price determination schema, which is not allowed in SAP.
  
  Cause:
  
  Configuration Conflict: The error arises when the system detects that the settlement schema (used for settling costs) is identical to the price determination schema (used for determining prices). This is not permitted because it can lead to inconsistencies in financial calculations and reporting.
  Incorrect Assignment: The assignment of schemas in the configuration settings may have been done incorrectly, leading to this overlap.
  
  
  Solution:
  To resolve this error, you need to ensure that the settlement schema and the price determination schema are different. Here are the steps to do that:
  
  
  Access Configuration:
  
  Go to the SAP Easy Access screen.
  Navigate to the configuration settings for
