• What is the cause and solution for SAP error message WRMA_CAT105 - Billing type &1: Maintain document schema for RMA cost allocation ?

  The SAP error message:
  WRMA_CAT105: Billing type &1: Maintain document schema for RMA cost allocation
  
  Cause:
  This error occurs because the system requires a document schema to be assigned to the billing type used in the Return Material Authorization (RMA) process for cost allocation purposes. The document schema controls how accounting documents are generated during billing. If the billing type used in RMA does not have an associated document schema, the system cannot proceed with cost allocation and billing.
  
  Explanation:
  
  In SAP RMA (Return Material Authorization) processes, billing types are used to generate billing documents.
  Each billing type must have a document schema assigned to it.
  The document schema defines the rules for posting accounting documents (e.g., which accounts to post to, how to handle taxes, etc.).
  If the billing type used in RMA is missing this assignment, the system throws the WRMA_CAT105 error.
  
  
  Solution:
  
  
  Identify the billing type causing the error:
  
  The error message will show the billing type (&1) that needs correction.
  
  
  
  Assign a document schema to the billing type:
  
  Go to SAP IMG (Implementation Guide):
  
  SPRO ? Sales and Distribution ? Billing ? Billing Documents ? Maintain Billing Types
  
  
  Select the billing type mentioned in the error.
  Assign the appropriate Document Schema to this billing type.
  
  Document schemas are usually defined in:
  
  SPRO ? Financial Accounting ? Financial Accounting Global Settings ? Document ? Document Header ? Define Document Types
  Or in SD billing settings under billing document types.
  
  
  
  
  
  
  
  Check RMA Cost Allocation settings:
  
  Ensure that the billing type is correctly configured for RMA cost allocation.
  Verify that the billing type is allowed for RMA billing.
  
  
  
  Test the process again:
  
  After assigning the document schema, try to process the RMA billing again to confirm the error is resolved.
  
  
  
  
  Additional Information:
  
  Document schemas are critical for controlling how billing documents post to accounting.
  Missing or incorrect document schema assignments can cause errors not only in RMA but also in other billing scenarios.
  If unsure which document schema to assign, consult your FI/CO or SD configuration team.
  Sometimes, custom billing types created for RMA processes may not have all necessary configurations; ensure all required settings are maintained.
