WRMA_CAT106 - Details

• SAP Error Message:
  WRMA_CAT106 – Billing type &1: Maintain calculation schema determination
  
  
  Cause:
  This error occurs because the billing type you are using in the billing document does not have a calculation schema assigned to it in the system. The calculation schema controls how pricing and taxes are calculated during billing. Without a valid calculation schema determination for the billing type, the system cannot proceed with pricing calculations, resulting in this error.
  
  Explanation:
  
  Billing Type: Defines the kind of billing document (e.g., invoice, credit memo).
  Calculation Schema: Defines the pricing procedure and rules applied during billing.
  The system requires a link between the billing type and the calculation schema to know which pricing procedure to use.
  If this link is missing or incorrectly maintained, the system throws the WRMA_CAT106 error.
  
  
  
  Solution:
  You need to maintain the calculation schema determination for the billing type in the customizing settings.
  Steps to resolve:
