  SAP Error Message:
  WRMA_CAT104 Billing type &1: Set "negative net value" to '1' (Allowed)
  
  Cause:
  This error occurs during billing document processing in SAP when the system encounters a billing type that does not allow negative net values, but the document being processed contains a negative net value (e.g., credit memo or returns with negative amounts).
  In SAP SD (Sales and Distribution), each billing type has a configuration setting that controls whether negative net values are allowed or not. If this setting is not enabled (set to '1'), and the billing document has a negative net value, the system throws this error.
  
  Explanation:
  
  Billing Type: A key that defines the characteristics of a billing document (e.g., invoice, credit memo, debit memo).
  Negative Net Value: A billing document with a net value less than zero, typically credit memos or returns.
  The system checks the billing type configuration to see if negative net values are allowed.
  If not allowed, and a negative net value is present, the error is raised.
  
  
  Solution:
  To resolve this error, you need to configure the billing type to allow negative net values.
  Steps:
  
  
  Go to SPRO (SAP Reference IMG):
  
  SPRO -> SAP Reference IMG -> Sales and Distribution -> Billing -> Billing Documents -> Define Billing Types
  
  
  Select the Billing Type:
  
  Find the billing type mentioned in the error message (the placeholder &1 will be replaced by the actual billing type in your system).
  
  
  Set "Negative Net Value" to Allowed:
  
  In the billing type configuration, there is a checkbox or field labeled "Negative net value" or similar.  
  
  Set this field to '1' (Allowed).
  
  
  
  Save the configuration.
  
  
  Reprocess the billing document or create a new billing document with the same billing type.
  
  
  
  Additional Information:
  
  This setting is important for handling credit memos, returns, or any billing documents that might have negative values.
  If you do not want to allow negative net values for a billing type, ensure that the billing documents created with that type do not have negative net values.
  Always test changes in a development or quality system before transporting to production.
  The error message is part of the standard SAP validation to prevent inconsistent billing data.
