  Assigned procedure for billing category & on header level &
  
  1. Cause
  This error occurs during billing document processing when the system detects that the billing procedure assigned to a particular billing category at the header level is missing or not properly maintained.
  In other words, the system expects a billing procedure to be assigned for the billing category in the billing document header, but it cannot find one. This usually happens because:
  
  The billing procedure is not assigned to the billing category in the customizing.
  The billing category used in the document header does not have a corresponding billing procedure.
  There is inconsistency or missing configuration in the billing procedure assignment.
  
  
  2. Where does it occur?
  
  During billing document creation (e.g., VF01 transaction).
  When the system tries to determine the billing procedure based on the billing category.
  In SD Billing (Sales and Distribution module).

  Maintain Billing Procedure Assignment:
  
  Go to SPRO ? SAP Reference IMG ? Sales and Distribution ? Billing ? Billing Documents ? Define Billing Procedures.

  Verify Billing Procedure:
  
  Check if the billing procedure assigned is correctly configured and active.
  Make sure the billing procedure includes all necessary steps and condition types.
  
  
  
  Check Copy Control:
  
  Sometimes, the error can be related to copy control settings between sales documents and billing documents.
  Verify the copy control settings in SPRO under Sales and Distribution ? Billing ? Copying Control.
  
  
  
  Test Billing Document Creation:
  
  After maintaining the assignment, try creating the billing document again.
