  The SAP error message WB2B345 indicates that a copy group for a differential invoice does not exist in the system. This error typically arises in the context of billing or invoicing processes, particularly when dealing with differential invoices in SAP.
  Cause:
  
  Missing Copy Group: The primary cause of this error is that the copy group specified in the invoice processing does not exist in the system. Copy groups are used to define how documents are copied or referenced in billing processes.
  Configuration Issues: There may be a configuration issue in the billing settings where the copy group for differential invoices has not been defined or has been incorrectly set up.

  Check Copy Group Configuration:
  
  Go to the SAP Customizing Implementation Guide (IMG) and navigate to the relevant section for billing document configuration.

  Sales and Distribution (SD) > Billing > Billing Documents > Define Copy Control for Billing Documents.
  
  
  Ensure that the copy group you are trying to use is correctly set up and exists in the system.
  
  
  
  Create or Modify Copy Group:
  
  If the copy group does not exist, you may need to create it. This involves defining the source and target document types and specifying the rules for copying data between them.
  If it exists but is not configured correctly, modify the settings to ensure it meets the requirements for differential invoices.
  
  
  
  Check Document Type:
  
  Ensure that the document type you are using for the differential invoice is compatible with the copy group. You may need to adjust the document type settings or use a different one that aligns with the existing copy group.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP support team for specific details on how to set up copy groups for differential invoices.
